Description
These optocouplers are similar to HP’s other high speed transistor optocouplers but with shorter propagation delays and higher CTR. The HCPL-4504/0454 and HCNW4504 also have a guaran­teed propagation delay difference (t
PLH
- t
PHL
). These features make these optocouplers an excellent solution to IPM inverter dead time and other switching problems.

The HCPL-4504/0454 and HCNW4504 CTR, propagation delay, and CMR are specified for both TTL and IPM load/drive conditions. Specifications and typical performance plots for both TTL and IPM conditions are provided for ease of application.
These single channel, diode­transistor optocouplers are available in 8-Pin DIP, SO-8, and Widebody package configura­tions. An insulating layer between a LED and an integrated photodetector provide electrical insulation between input and output. Separate connections for

7. Under TTL load and drive conditions: Common mode transient immunity in a Logic High level is the maximum tolerable (positive) dVCM/dt on the leading edge of the common mode pulse, VCM, to assure that the output will remain in a Logic High state (i.e., VO> 2.0 V). Common mode transient immunity in a Logic Low level is the maximum tolerable (negative) dVCM/dt on the trailing edge of the common mode pulse signal, VCM, to assure that the output will remain in a Logic Low state (i.e., VO < 0.8 V).

Power Inverter Dead Time and Propagation Delay Specifications
The HCPL-4504/0454 and HCNW4504 include a specifica­tion intended to help designers minimize “dead time” in their power inverter designs. The new “propagation delay difference” specification (t
PLH-tPHL
) is useful for determining not only how much optocoupler switching delay is needed to prevent “shoot­through” current, but also for determining the best achievable worst-case dead time for a given design.
When inverter power transistors switch (Q1 and Q2 in Figure 17), it is essential that they never
Page 16
1-48
time is the sum of the maximum difference in turn-on delay plus the maximum difference in turn­off delay,
[(t
PLHmax-tPLHmin
)+(t
PHLmax-tPHLmin
)].
This expression can be rearranged to obtain
[(t
PLHmax-tPHLmin
)-(t
PHLmin-tPHLmax
)],
and further rearranged to obtain
[(t
PLH-tPHL)max
-(t
PLH-tPHL)min
],
which is the maximum minus the minimum data sheet values of (t
PLH-tPHL
). The difference between the maximum and minimum values depends directly on the total spread in propagation delays and sets the limit on how good the worst-case dead time can be for a given design. Therefore, optocouplers with tight propagation delay specifications (and not just shorter delays or lower pulse-width distortion) can achieve short dead times in power inverters. The HCPL-4504/0454 and HCNW4504 specify a minimum (t
PLH-tPHL
) of -0.7 µs
over an operating temperature range of 0-70°C, resulting in a maximum dead time of 2.0 µs when the LED turn-on delay is equal to (t
PLH-tPHL
)
max
, or 1.3 µs.
It is important to maintain accurate LED turn-on delays because delays shorter than (t
PLH-tPHL
)
max
may allow shoot­through currents, while longer delays will increase the worst-case dead time.
conduct at the same time. Extremely large currents will flow if there is any overlap in their conduction during switching transitions, potentially damaging the transistors and even the sur­rounding circuitry. This “shoot­through” current is eliminated by delaying the turn-on of one transistor (Q2) long enough to ensure that the opposing transistor (Q1) has completely turned off. This delay introduces a small amount of “dead time” at the output of the inverter during which both transistors are off during switching transitions. Minimizing this dead time is an important design goal for an inverter designer.
The amount of turn-on delay needed depends on the propaga­tion delay characteristics of the optocoupler, as well as the characteristics of the transistor base/gate drive circuit. Consider­ing only the delay characteristics of the optocoupler (the charac­teristics of the base/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 importance of these specifications is illustrated in Figure 17. The waveforms labeled “LED1”, “LED2”, “OUT1”, and “OUT2” are the input and output voltages of the optocoupler circuits driving Q1 and Q2 respectively. Most inverters are designed such that the power transistor turns on when the optocoupler LED turns on; this ensures that both power transistors will be off in the event of a power loss in the control circuit. Inverters can also be designed such that the power
transistor turns off when the optocoupler LED turns on; this type of design, however, requires additional fail-safe circuitry to turn off the power transistor if an over-current condition is detected. The timing illustrated in Figure 17 assumes that the power transistor turns on when the optocoupler LED turns on.
The LED signal to turn on Q2 should be delayed enough so that an optocoupler with the very fastest turn-on propagation delay (t
PHLmin
) will never turn on before an optocoupler with the very slowest turn-off propagation delay (t
PLHmax
) turns off. To ensure this, the turn-on of the optocoupler should be delayed by an amount no less than (t
PLHmax-tPHLmin
), which also happens to be the maximum data sheet value for the propagation delay difference specification, (t
PLH-tPHL
). The HCPL-4504/0454 and HCNW4504 specify a maximum (t
PLH-tPHL
) of 1.3 µs over an
operating temperature range of 0-70°C.
Although (t
PLH-tPHL
)
max
tells the designer how much delay is needed to prevent shoot-through current, it is insufficient to tell the designer how much dead time a design will have. Assuming that the optocoupler turn-on delay is exactly equal to (t
PLH
- t
PHL
)
max
, the minimum dead time is zero (i.e., there is zero time between the turn-off of the very slowest optocoupler and the turn-on of the very fastest optocoupler).
Calculating the maximum dead time is slightly more complicated. Assuming that the LED turn-on delay is still exactly equal to (t
PLH-tPHL
)
max
, it can be seen in
Figure 17 that the maximum dead
