NDESCRIPTION

The MP1922 is a 100V, single-channel,

integrated circuit (IC), half-bridge gate driver

designed for motor driver applications and other

power control applications. The two N-channel

power MOSFETs are set up in a half H-bridge

configuration, and operate on power supplies

up to 100V.

The MP1922 combines a bootstrap (BST)

capacitor and an internal charge pump to

generate a supply voltage of the high-side

MOSFET (HS-FET) driver. The device’s HSFET

driver generates a voltage above the

power supply, which in many cases indefinitely

maintains a high output at 100 duty cycle

operation.

The half-bridge pre-driver features configurable

slew rate control, FET desaturation protection,

adjustable dead-time control, under-voltage

lockout (UVLO), and thermal shutdown.

The MP1922 is available in a QFN-22

(4mmx5mm) package with an exposed thermal

pad.
