DESCRIPTION

The MP6529 is a gate driver IC designed for

three-phase,

brushless

DC

motor

driver

applications; it is capable of driving three half-

bridges consisting of six N-channel power

MOSFETs up to 35V.

The MP6529 uses a bootstrap capacitor to

generate a supply voltage for the high-side

MOSFET driver. An internal trickle-charge

circuit maintains a sufficient gate driver voltage

at 100% duty cycle.

Full protection features include programmable

over-current protection (OCP), adjustable dead-

time control, under-voltage lockout (UVLO), and

thermal shutdown.

The MP6529 is available in a 28-pin TSSOP

(9.7mmx6.4mm) package with an exposed

thermal pad and a 28-contact QFN (4mmx4mm)

package with an exposed thermal pad.
