The INA203, INA204, and INA205 are a family of unidirectional current-shunt monitors with voltage output, dual comparators, and voltage reference. The INA203, INA204, and INA205 can sense drops across shunts at common-mode voltages from – 16V

available with three output voltage scales: 20V/V, 50V/V, and 100V/V, with up to 500kHz bandwidth.

The INA203, INA204, and INA205 also incorporate two open-drain comparators with internal 0.6V references. On 14-pin versions, the comparator references can be overridden by external inputs. Comparator 1 includes a latching capability, and Comparator 2 has a user-programmable delay. 14-pin versions also provide a 1.2V reference output.

The INA203, INA204, and INA205 operate from a single +2.7V to +18V supply. They are specified over the extended operating temperature range of – 40 ° C to +125 ° C.

(1) The INA203, INA204, and INA205 are designed to power-up with the comparator in a defined reset state as long as CMP1 RESET is

open or grounded. The comparator will be in reset as long as the power supply is below the voltage shown here. The comparator assumes a state based on the comparator input above this supply voltage. If CMP1 RESET is high at power-up, the comparator output comes up high and requires a reset to assume a low state, if appropriate.

Figure 30 shows the basic connections of the

INA203, INA204, and INA205. The input pins, V and V

to the shunt resistor to minimize any resistance in series with the shunt resistance.

Power-supply bypass capacitors are required for stability. Applications with noisy or high-impedance power supplies may require additional decoupling capacitors to reject power-supply noise. Connect • Low V bypass capacitors close to the device pins. 80V

POWER SUPPLY

The input circuitry of the INA203, INA204, and INA205 can accurately measure beyond the power-supply voltage, V+. For example, the V+ power supply can be 5V, whereas the load power-supply voltage is up to +80V. The output voltage range of the OUT terminal, however, is limited by the voltages on the power-supply pin.

ACCURACY VARIATIONS AS A RESULT OF V

The accuracy of the INA203, INA204, and INA205 current shunt monitors is a function of two main variables: V voltage, V expressed as (V V voltage drop across V

This region of operation is the least accurate for the INA203 family. To achieve the wide input common-mode voltage range, these devices use two op amp front ends in parallel. One op amp front end operates in the positive input common-mode voltage range, and the other in the negative input region. For this case, neither of these two internal amplifiers dominates and overall loop gain is very low. Within this region, V

SELECTING R

SHUNT

The value chosen for the shunt resistor, R depends on the application and is a compromise between small-signal accuracy and maximum permissible voltage loss in the measurement line. High values of R

SHUNT

provide better accuracy at lower currents by minimizing the effects of offset, while low values of R

minimize voltage loss in

the supply line. For most applications, best performance is attained with an R provides a full-scale shunt voltage range of 50mV to 100mV. Maximum input voltage for accurate measurements is (V

– 0.25)/Gain.

SHUNT

TRANSIENT PROTECTION

The – 16V to +80V common-mode range of the INA203, INA204, and INA205 is ideal for withstanding automotive fault conditions ranging from 12V battery reversal up to +80V transients, since no additional protective components are needed up to those levels. In the event that the INA203, INA204, and INA205 are exposed to transients on the inputs in excess of their ratings, then external transient absorption with semiconductor transient absorbers (zeners or Transzorbs) are necessary. Use of metal oxide varistors (MOVs) or video disk recorders (VDRs) is not recommended except when they are used in addition to a semiconductor transient absorber. Select the transient absorber such that it will never allow the INA203, INA204, and INA205 to be exposed to transients greater than +80V (that is,

SENSE

SHUNT

allow for transient absorber tolerance, as well as additional voltage because of transient absorber dynamic impedance). Despite the use of internal zener-type ESD protection, the INA203, INA204, and INA205 do not lend themselves to using external resistors in series with the inputs because the internal gain resistors can vary up to ± 30% but are closely matched. (If gain accuracy is not important, then resistors can be added in series with the INA203, INA204, and INA205 inputs with two equal resistors on each input.)

OUTPUT VOLTAGE RANGE

The output of the INA203, INA204, and INA205 is accurate within the output voltage swing range set by the power-supply pin, V+. This performance is best

illustrated when using the INA205 (a gain of 100 version), where a 100mV full-scale input from the shunt resistor requires an output voltage swing of +10V, and a power-supply voltage sufficient to achieve +10V on the output.

INPUT FILTERING

An obvious and straightforward location for filtering is at the output of the INA203, INA204, and INA205 series; however, this location negates the advantage of the low output impedance of the internal buffer. The only other option for filtering is at the input pins of the INA203, INA204, and INA205, which is complicated by the internal 5k Ω + 30% input impedance; this configuration is illustrated in

Figure 33 . Using the lowest possible resistor values

minimizes both the initial shift in gain and effects of tolerance. The effect on initial gain is given by

Equation 3 :

Total effect on gain error can be calculated by replacing the 5k Ω term with 5k Ω – 30%, (or 3.5k Ω ) or 5k Ω + 30% (or 6.5k Ω ). The tolerance extremes of R

REFERENCE

COMPARATOR DELAY (14-Pin Version Only)

The Comparator 2 programmable delay is controlled

by a capacitor connected to the CMP2 Delay Pin; see The INA203, INA204, and INA205 include an internal Figure 30 . The capacitor value (in μ F) is selected by voltage reference that has a load regulation of using Equation 4 :

0.4mV/mA (typical), and not more than 100ppm/ ° C of drift. Only the 14-pin package allows external access to reference voltages, where voltages of 1.2V and

0.6V are both available. Output current versus output A simplified version of the delay circuit for voltage is illustrated in the Typical Characteristics Comparator 2 is shown in Figure 34 . The delay section. comparator consists of two comparator stages with

COMPARATOR

The INA203, INA204, and INA205 devices incorporate two open-drain comparators. These comparators typically have 2mV of offset and a 1.3 μ s (typical) response time. The output of Comparator 1 latches and is reset through the CMP1 RESET pin, as shown in Figure 35 . This configuration applies to both the 10- and 14-pin versions. Figure 34 illustrates the comparator delay.

low output and I2 corresponds to a U1 high output.

Using an initial assumption that the U1 output is low,

I1 is on, then U2 +IN is zero. If U1 goes high, I2

supplies 120nA to C

. The voltage at U2 +IN

begins to ramp toward a 0.6V threshold. When the

voltage crosses this threshold, the U2 output goes

behavior with events more rapid than its delay setting, use the model shown in Figure 34 .

COMPARATOR MAXIMUM INPUT VOLTAGE RANGE

The maximum voltage at the comparator input for normal operation is up to (V+) – 1.5V. There are special considerations when overdriving the reference inputs (pins 3 and 6). Driving either or both inputs high enough to drive 1mA back into the reference introduces errors into the reference. Figure 36 shows the basic input structure. A general guideline is to limit the voltage on both inputs to a total of 20V. The exact limit depends on the available voltage and

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.

TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.

TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions.

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
