Core Logic Power ( Input ) - Low voltage power supply for internal logic.
Control Interface and PWM Input Power ( Input ) - Supply for the I/O.
Ground ( Input ) - Ground for the internal logic and I/O. These pins should be connected to the
common system ground.
PWM Output ( Output ) - Amplified PWM power half-bridge outputs.
PWM Input ( Input ) - Inputs from a PWM modulator. These pins should not be left floating.
Reset Input ( Input ) - Reset inputs for channel 1, 2, 3, and 4; active low. These pins should not be
left floating.
Over-Current Error Output ( Output ) - Over-current error flag for OUTx. Open drain with internal
pull-up, active low. See
Thermal and Under-Voltage Error Output ( Output ) - Error flag for thermal shutdown and under-
voltage. Open drain with internal pull-up, active low. See
page 18
Thermal Warning Output ( Output ) - Thermal warning output. Open drain with internal pull-up,
active low. See
Input Voltage Level Select ( Output ) - Input voltage indicator of VD. A high level indicates VD is
set to 5.0 V. A low level indicates VD is set to 3.3 V. This pins should not be left floating.
Mode Select ( Input ) - Used to set the operating mode. See
page 15
Over-Current Reference ( Input ) - Over-current trip level setting. This pin should be connected
through a 60 k Ω resistor to GND. See
This pins should not be left floating.
Ramp-Up/Down Select ( Input ) - When set high, ramping is enabled. When set low, ramping is
disabled. See
be left floating. Ramp should only be used in half bridge mode or in full bridge configuration
modes 010 and 011.
