BOOT
Bootstrap Supply Input.
Connect to bootstrap capacitor and diode.
PWM Signal Input.
Accepts a logic-level PWM signal from the controller.
Output Disable.
When low, this pin disables FET switching (HDRV and LDRV are
held low).
Power Input
. +12V bias power. Bypass with a 1μF ceramic capacitor.
Low Side Gate Drive Output.
Connect to the gate of the low-side power MOSFET(s).
Power Ground.
Connect directly to the source of low-side MOSFET(s) and C
Switch Node Input
. Connect as shown in Figure 1. SW provides return for the high-side
bootstrapped driver and acts as a sense point for the adaptive shoot-thru protection.
Provides voltage supply to the high-side MOSFET driver.
