Over-current Reference (Input) - Sets over-current trip level. Connect pin through a resistor to
GND. See
ing.
Output Ramp Capacitor (Input) - Sets the output ramp time for half-bridge configured outputs.
Ground (Input) - Ground for the internal logic and I/O. These pins should be connected to the
common system ground.
High Voltage Output Power (Input) - High voltage power supply for the individual output power
half-bridge devices.
Power Ground (Input) - Ground for the individual output power half-bridge devices. These pins
should be connected to the common system ground.
PWM Output (Output) - Amplified PWM power half-bridge outputs.
Thermal Warning Output (Output) - Thermal warning output. Open drain, active low. See
“Device Protection and Error Reporting” on page
Thermal and Under-voltage Error Output (Output) - Error flag for thermal shutdown and under-
voltage. Open drain, active low. See
Over-current Error Output (Output) - Over-current error flag for the associated outputs. Open
drain, active low. See
Ramp-up/down Select (Input) - Set high to enable ramping. When set low, ramping is disabled.
