Pin Descriptions

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, which will generally 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.
