DESCRIPTION

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 to +80V. The INA203, INA204, and INA205 are 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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1)Hysteresis refers to the threshold (the threshold specification applies to a rising edge of a noninverting input) of a falling edge on the noninverting input of the comparator; refer to Figure 1.

(2)Specified by design; not production tested.

(3)See the Comparator Maximum Input Voltage Range section in the Applications Information.

(4)The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4V.

(5)The CMP1 RESET input has an internal 2MΩ (typical) pull-down. Leaving the CMP1 RESET open results in a LOW state, with transparent comparator operation.

(6)The Comparator 2 delay applies to both rising and falling edges of the comparator output.

(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.
