Description
Enable Input. Pull pin LOW to inhibit driver. EN has logic thresholds for both
TTL and CMOS IN thresholds.
Ground. Common ground reference for input and output circuits.
Input.
Gate Drive Output. Held LOW unless required input is present and VDD is
above the UVLO threshold.
Gate Drive Output (inverted from the input). Held LOW unless required
input is present and VDD is above the UVLO threshold.
Supply Voltage. Provides power to the IC.
