Out Configuration Select (Input) - Used to set the PWM output configuration mode. See
Mode Configuration” on page
PWM Input (Input) - Logic-level switching inputs from a PWM modulator.
Reset Input (Input) - Reset inputs for channels 1/2 and 3/4, respectively. Active low.
VD Voltage Level Indicator (Input) - Identifies the voltage level attached to VD. When applying
5.0 V to VD, LVD must be connected to VD. When applying 2.5 V or 3.3 V to VD, LVD must be
GND.
Core Digital Power (Output) - Internally generated low voltage power supply for digital logic.
Digital Power (Input) - Positive power supply for the internal regulators and digital I/O.
Over-current Reference (Input) - Sets over-current trigger level. Connect pin through a resistor
to GND. See
