ACPL-33JT

Data Sheet

Electrical Specifications

Unless otherwise specified, all Minimum/Maximum specifications are at recommended operating conditions, all voltages at input

IC are referenced to VEE1, all voltages at output IC are referenced to VEE2. All typical values at TA = 25 °C, VCC1 = 5 V, VCC2 – VEE2 = 16 V.

In most applications, VCC1 will be powered up first (before VCC2) and powered down last (after VCC2). This is desirable for maintaining control of the IGBT

gate. In applications where VCC2 is powered up first, it is important to ensure that the input remains low until VCC1 reaches the proper operating voltage

to avoid any momentary instability at the output during VCC1 ramp-up or ramp-down).

15.2V is the recommended minimum operating supply voltage (VCC2 – VEE2) to ensure adequate margin in excess of the maximum VUVLO+ threshold of 14.5V.
