The LED is optically coupled to an integrated circuit with a power output stage. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. Wide operating VCC range: 15 to 30? Industrial temperature range:? Industrial inverters?? Switch mode power supplies A 0. F bypass capacitor must be connected between pins 5 and 8. Contact Avago sales representative or authorized distributor. To order, choose a part number from the part number column and combine with the desired option from the option column to form an order entry.

Option datasheets are available. Contact your Avago sales representative or authorized distributor for information. Lot ID 1. Conditions Measured from input terminals to output terminals, shortest distance through air.

When negative gate drive is not used VEE in the previous equation is equal to zero volts. The HCPL total power dissipa? J 20 kHz?? The thermal resistance values given in this model can be used to calculate the tempera? As shown by the model, all heat generated flows through qCA which raises the case temperature TC accordingly.

The value of qCA depends on the conditions of the board design and is, therefore, determined by the designer. The value of qCA? The absolute maximum power dissipation derating specifica? Thermal model. 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.

For example, the recommended application circuit Figure 25 , can achieve 25? Techniques to keep the LED in the proper state are discussed in the next two sections. Optocoupler input to output capacitance model for unshielded optocouplers. Optocoupler input to output capacitance model for shielded optocouplers. This is achieved by overdriving the LED current beyond the input threshold so that it is not pulled below the threshold during a transient.

Dead time is the time period during which both the high and low side power transistors Q1 and Q2 in Figure 25 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.
