When SMOD# = HI, low side driver is inverse of PWM input. When SMOD# = Low, low
side driver is disabled. This pin has no internal pullup or pulldown. It should not be left
floating. Do not add noise filter cap.
IC bias supply. Minimum 1 F ceramic capacitor is recommended from this pin to CGND.
Power for low side driver. Minimum 1 F ceramic capacitor is recommended to be
connected as close as possible from this pin to CGND.
Bootstrap supply input. Provides voltage supply to high-side MOSFET driver. Connect
bootstrap capacitor from this pin to PHASE.
IC ground. Ground return for driver IC.
For manufacturing test only. This pin must be floated. Must not be connected to any pin.
Switch node pin for easy bootstrap capacitor routing. Electrically shorted to VSWH pin.
No connect.
Power input. Output stage supply voltage.
Switch node input. Provides return for high-side bootstrapped driver and acts as a
sense point for the adaptive shoot-thru protection.
Power ground. Output stage ground. Source pin of low side MOSFET(s).
For manufacturing test only. This pin must be floated. Must not be connected to any pin.
Output disable. When low, this pin disable FET switching (GH and GL are held low). This
pin has no internal pullup or pulldown. It should not be left floating. Do not add noise filter
cap.
PWM Signal Input. This pin accepts a logic-level PWM signal from the controller. This pin
has no internal pullup or pulldown. It should not be left floating. Do not add noise filter cap.
