DESCRIPTION

The MP6530 is a gate driver IC designed for

three-phase

brushless

DC

motor

driver

applications. It is capable of driving three half

bridges

consisting

of

6

N-channel

power

MOSFETs up to 60V.

The MP6530 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 MP6530 is available in 28-pin, 9.7mm ×

6.4mm

TSSOP

and

4mm

x

4mm

QFN

packages with an exposed thermal pad.
