Overview

The MP6532GR-Z 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 60V.The MP6532GR-Z 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, under-voltage lockout, and thermal shutdown.The device integrates 120° commutation using three Hall sensor inputs. The PWM, DIR, and nBRAKE inputs are used to control motor speed, direction, and braking.The MP6532GR-Z is available in 28-pin, 9.7mm × 6.4mm TSSOP and 4mm x 4mm QFN packages with an exposed thermal pad. Bostock Electronics is an authorized Monolithic Power Systems distributor.
