Descriptions

Input power supply to IC and lower gate drivers

HB

Floating boostrap supply for the upper MOSFET. External bootstrap capacitor is required

HO

Output drive for upper MOSFET. Connect to gate of upper power MOSFET

HS

Floating GND for the upper MOSFET. Connect to source of upper power MOSFET

HI

Input for upper drive

LI

Input for lower drive

Ground supply

LO

Output drive for lower MOSFET. Connect to gate of lower power MOSFET

PowerPAK

Exposed PowerPAK is for heat dissipation. Exposed PowerPAK is floating or grounded. The PowerPad is not

guaranteed electrically isolated from all other pins
