DESCRIPTION

The MP6528 is a gate driver IC designed for H-

bridge driver applications. It is capable of

driving two half-bridges consisting of four N-

channel power MOSFETs up to 60V.

The MP6528 integrates a regulated charge

pump to generate gate drive power, and uses a

bootstrap

capacitor

to

generate

a

supply

voltage for the high-side MOSFET driver. An

internal trickle-charge circuit maintains sufficient

high-side gate driver voltage even when an

output is operated at 100% duty cycle.

Internal

protection

features

include

programmable short-circuit protection, over-

current protection, adjustable dead-time control,

undervoltage lockout, and thermal shutdown.

The

MP6528

is

available

in

a

QFN-28

(4mmx4mm) package with an exposed thermal

pad.
