HCPL-4504-000E

Data Sheet HCPL-4504/J454/0454, HCNW4504 High CMR, High-Speed Optocouplers Description The Broadcom® HCPL-4504 and HCPL-0454 contain a GaAsP LED while the Broadcom HCPL-J454 and HCNW4504 contain an AlGaAs LED. The LED is optically coupled to an integrated high-gain photodetector. The HCPL-4504 series has short propagation delays and high CTR. The HCPL-4504 series also has a guaranteed propagation delay difference (tPLH – tPHL). These features make the HCPL-4504 series an excellent solution to IPM inverter dead time and other switching problems. The CTR, propagation delay, and CMR are specified both for TTL and IPM conditions, which are provided for ease of application. These single channel, diode-transistor optocouplers are available in 8-Pin DIP, SO-8, and Widebody package configurations. An insulating layer between an LED and an integrated photodetector provide electrical insulation between input and output. Separate connections for the photodiode bias and output-transistor collector increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base collector capacitance. CAUTION! Take normal static precautions in handling and assembly of this component to prevent damage, degradation, or both that may be induced by ESD.

These dimensions are needed as a starting point for the equipment designer when determining the circuit insulation requirements. However, when mounted on a printed circuit board, minimum creepage and clearance requirements must be met as specified for individual equipment standards. For creepage, consider the shortest distance path along the surface of a printed circuit board between the solder fillets of the input and output leads. There are techniques, such as grooves and ribs, that may be used on a printed circuit board to achieve desired creepage and clearances. Creepage and clearance distances also change depending on factors, such as pollution degree and insulation level.

The new “propagation delay difference” specification (tPLH – tPHL) is useful for determining not only how much optocoupler switching delay is needed to prevent “shoot-through” 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 conduct at the same time. Extremely large currents flow if there is any overlap in their conduction during switching transitions, potentially damaging the transistors and even the surrounding circuitry. This “shoot-through” 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. Broadcom 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 (tPHL) and turnoff (tPLH) 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 overcurrent condition is detected. The timing illustrated in Figure 17 assumes that the power transistor turns on when the optocoupler LED turns on. AV02-0867EN 25 HCPL-4504/J454/0454, HCNW4504 Data Sheet The LED signal to turn on Q2 should be delayed enough so that an optocoupler with the very fastest turn-on propagation delay (tPHLmin) never turns on before an optocoupler with the very slowest turn-off propagation delay (tPLHmax) turns off. To ensure this, the turn-on of the optocoupler should be delayed by an amount no less than (tPLHmax – tPHLmin), which also happens to be the maximum data sheet value for the propagation delay difference specification, (tPLH – tPHL). The HCPL-4504/0454/J454 and HCNW4504 specify a maximum (tPLH – tPHL) of 1.3 µs over an operating temperature range of 0°C to 70°C. Although (tPLH – 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 (tPLH – tPHL)max, the minimum dead time is zero (that is, 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 (tPLH – tPHL)max, it can be seen in Figure 17 that the maximum dead time is the sum of the maximum difference in turn-on delay plus the maximum difference in turnoff delay, High CMR, High-Speed Optocouplers This expression can be rearranged to obtain [(tPLHmax – tPHLmin) – (tPHLmin – tPHLmax)], and further rearranged to obtain [(tPLH – tPHL)max – (tPLH – tPHL)min], which is the maximum minus the minimum data sheet values of (tPLH – 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/J454 and HCNW4504 specify a minimum (tPLH – tPHL) of –0.7 µs over an operating temperature range of 0°C to 70°C, resulting in a maximum dead time of 2.0 µs when the LED turn-on delay is equal to (tPLH – tPHL)max, or 1.3 µs. It is important to maintain accurate LED turn-on delays because delays shorter than (tPLH – tPHL)max may allow shoot-through currents, while longer delays will increase the worst-case dead time. [(tPLHmax – tPLHmin) + (tPHLmax – tPHLmin)].
