Bootstrap Supply Input . Provides voltage supply to high-side MOSFET driver.
Connect to bootstrap capacitor (typically 100nF to 1µF). See Applications
Section for detailed information.
PWM Signal Input . This pin accepts a digital logic-level PWM switching signal
from the controller.
Output Disable . When low, this pin disables PWM switching and pulls DRVH
and DRVL low.
Power Input . +12V chip bias power. Bypass with a 1µF ceramic capacitor.
Low Side Gate Drive Output . Connect to the gate of low-side power
MOSFET(s).
Power Ground . Power ground connect close to low-side MOSFET to minimize
ground loops.
Switch Node Input . Connect to switching node between HS and LS MOSFETs.
It is necessary for adaptive shoot-thru protection. Also it provides return for
high-side bootstrapped driver.
High Side Gate Drive Output . Connect to the gate of high-side power
MOSFET(s).
