products are capable of operation and storage over the full military temperature range and can be purchased as either standard product or with full MIL-PRF­38534 Class Level H or K testing or from the DESC Drawing 5962-
96852. All devices are manufactured and tested on a MIL-PRF-38534 certified line and are included in the DESC Qualified Manufacturers List QML-38534 for Hybrid Micro­circuits. Minimized propagation delay difference between devices make these optocouplers excellent solutions for improving inverter efficiency through reduced switching dead time. An on chip 20 k output pull-up resistor can be enabled by shorting output pins 6 and 7, thus eliminating the need for an external pull-up resistor in common IPM applica­tions. Specifications and performance plots are given for typical IPM applications.

LED Drive Circuit Considerations For Ultra High CMR Performance
Without a detector shield, the dominant cause of optocoupler CMR failure is capacitive coupling from the input side of the optocoupler, through the package, to the detector IC as shown in Figure 14. The HCPL­5300/5301 improves CMR performance by using a detector IC with an optically transparent Faraday shield, which diverts the capacitively coupled current away from the sensitive IC circuitry. However, this shield does not eliminate the capacitive coupling between the LED and the opto­coupler output pins and output ground as shown in Figure 15. This capacitive coupling causes perturbations in the LED current during common mode transients and becomes the major source of CMR failures for a shielded optocoupler. The main design objective of a high CMR LED drive circuit becomes keeping the LED in the proper state (on or off) during common mode transients. For example, the recommended application circuit (Figure 13), can achieve 10 kV/µs CMR while minimizing compo­nent complexity. Note that a CMOS gate is recommended in Figure 13 to keep the LED off when the gate is in the high state.
Another cause of CMR failure for a shielded optocoupler is direct coupling to the optocoupler output pins through C
LEDO1
and
C
LEDO2
in Figure 15. Many factors influence the effect and magni­tude of the direct coupling including: the use of an internal or external output pull-up resistor, the position of the LED current setting resistor, the connection of the unused input
package pins, and the value of the capacitor at the optocoupler output (CL).
Techniques to keep the LED in the proper state and minimize the effect of the direct coupling are discussed in the next two sections.
CMR With The LED On (CMRL)
A high CMR LED drive circuit must keep the LED on during common mode transients. This is achieved by overdriving the LED current beyond the input threshold so that it is not pulled below the threshold during a transient. The recommended minimum LED current of 10 mA provides adequate margin over the maximum ITH of 5.0 mA (see Figure 1) to achieve 10 kV/µs CMR. Capacitive coupling is higher when the internal load resistor is used (due to C
LEDO2
)
and an IF= 16mA is required to obtain 10 kV/µs CMR.
The placement of the LED current setting resistor affects the ability of the drive circuit to keep the LED on during transients and interacts with the direct coupling to the optocoupler output. For example, the LED resistor in Figure 16 is connected to the anode. Figure 17 shows the AC equivalent circuit for Figure 16 during common mode transients. During a +dV
CM/dt
in Figure 17, the current available at the LED anode (I
TOTAL
) is limited by the series resistor. The LED current (IF) is reduced from its DC value by an amount equal to the current that flows through C
LEDP
and
C
LEDO1
. The situation is made worse because the current through C
LEDO1
has the effect of
trying to pull the output high
(toward a CMR failure) at the same time the LED current is being reduced. For this reason, the recommended LED drive circuit (Figure 13) places the current setting resistor in series with the LED cathode. Figure 18 is the AC equivalent circuit for Figure 13 during common mode transients. In this case, the LED current is not reduced during a +dV
CM/dt
transient because the current flowing through the package capacitance is supplied by the power supply. During a
-dV
CM/dt
transient, however, the LED current is reduced by the amount of current flowing through C
LEDN
. But better CMR performance is achieved since the current flowing in C
LEDO1
during a negative transient acts to keep the output low.
Coupling to the LED and output pins is also affected by the connection of pins 1 and 4. If CMR is limited by perturbations in the LED on current, as it is for the recommended drive circuit (Figure 13), pins 1 and 4 should be connected to the input circuit common. However, if CMR performance is limited by direct coupling to the output when the LED is off, pins 1 and 4 should be left unconnected.
CMR With The LED Off (CMRH)
A high CMR LED drive circuit must keep the LED off (VF≤ V
F(OFF)
) during common mode transients. For example, during a +dV
CM/dt
transient in Figure 18, the current flowing through C
LEDN
is supplied by the parallel combination of the LED and series resistor. As long as the voltage developed across the resistor is less than V
F(OFF)
the
LED will remain off and no
1-506
common mode failure will occur. Even if the LED momentarily turns on, the 100 pF capacitor from pins 6-5 will keep the output from dipping below the threshold. The recommended LED drive circuit (Figure 13) provides about 10 V of margin between the lowest optocoupler output voltage and a 3 V IPM threshold during a 10 kV/µs transient with VCM= 1000 V. Additional margin can be obtained by adding a diode in parallel with the resistor, as shown by the dashed line connec­tion in Figure 18, to clamp the voltage across the LED below V
F(OFF)
.
Since the open collector drive circuit, shown in Figure 19, cannot keep the LED off during a +dV
CM/dt
transient, it is not desirable for applications requiring ultra high CMR
H
performance. Figure 20 is the AC equivalent circuit for Figure 16 during common mode transients. Essentially all the current flowing through C
LEDN
during a +dV
CM/dt
transient must be supplied by the LED. CMRH failures can occur at dv/dt rates where the current through the LED and C
LEDN
exceeds the input threshold. Figure 21 is an alternative drive circuit which does achieve ultra high CMR performance by shunting the LED in the off state.
IPM Dead Time and Propagation Delay Specifications
These devices include a Propagation Delay Difference specification intended to help designers minimize “dead time” in their power inverter designs. Dead time is the time period during which both the high and low side power transistors (Q1 and Q2 in Figure 22) are off. Any overlap in Q1 and Q2 conduction will result in large currents flowing through the power devices between the high and low voltage motor rails.
To minimize dead time the designer must consider the propagation delay characteristics of the optocoupler as well as the characteristics of the IPM IGBT gate drive circuit. Considering only the delay characteristics of the optocoupler (the character­istics of the IPM IGBT gate drive circuit can be analyzed in the same way) it is important to know the minimum and maximum turn-on (t
PHL
) and turn-off (t
PLH
) propagation delay specifications, preferably over the desired operating temperature range.
The limiting case of zero dead time occurs when the input to Q1 turns off at the same time that the input to Q2 turns on. This case determines the minimum delay between LED1 turn-off and LED2
turn-on, which is related to the worst case optocoupler propaga­tion delay waveforms, as shown in Figure 23. A minimum dead time of zero is achieved in Figure 23 when the signal to turn on LED2 is delayed by (t
PLH max
-
t
PHL min
) from the LED1 turn off. This delay is the maximum value for the propagation delay difference specification which is specified at 500 ns for the HCPL­5300/5301 over an operating temperature range of -55°C to +125°C.
Delaying the LED signal by the maximum propagation delay difference ensures that the mini­mum dead time is zero, but it does not tell a designer what the maximum dead time will be. The maximum dead time occurs in the highly unlikely case where one optocoupler with the fastest t
PLH
and another with the slowest t
PHL
are in the same inverter leg. The maximum dead time in this case becomes the sum of the spread in the t
PLH
and t
PHL
propagation delays as shown in Figure 24. The maximum dead time is also equivalent to the difference between the maximum and minimum propagation delay difference specifications. The maximum dead time (due to the optocouplers) for the HCPL­5300/5301 is 670 ns (= 500 ns ­(-170 ns)) over an operating temperature range of -55°C to +125°C.
