FUNCTION
Bootstrap pin to provide bias for PWM2 high-side driver. The positive terminal of the bootstrap capacitor connects to this
pin. The bootstrap diodes are integrated to help reduce total cost and reduce layout complexity.
High-side MOSFET gate driver output for PWM2.
Low-side MOSFET gate driver output for PWM2.
Low-side MOSFET gate driver output for PWM1.
High-side MOSFET gate driver output for PWM1.
Bootstrap pin to provide bias for PWM1 high-side driver. The positive terminal of the bootstrap capacitor connects to this
pin. The bootstrap diodes are integrated to help reduce total cost and reduce layout complexity.
Phase node connection for PWM1. This pin is connected to the junction of the upper MOSFET’s source, output filter inductor,
and lower MOSFET’s drain. PHASE1 is the internal lower supply rail for UGATE1.
EPAD at ground potential. Solder it directly to GND plane for better thermal performance.
