SYMBOL

DESCRIPTION

HB

High-Side Bootstrap supply. External bootstrap capacitor is required. Connect positive side of bootstrap capacitor to this pin.

Bootstrap diode is on-chip.

HO

High-Side Output. Connect to gate of High-Side power MOSFET.

HS

High-Side Source connection. Connect to source of High-Side power MOSFET. Connect negative side of bootstrap capacitor to

this pin.

HI

High-Side input.

LI

Low-Side input.

Chip negative supply, generally will be ground.

LO

Low-Side Output. Connect to gate of Low-Side power MOSFET.

EPAD

Exposed pad. Connect to ground or float. The EPAD is electrically isolated from all other pins.
