MP6532 - Three-Phase Brushless DC Motor Pre-Driver

General Description

The MP6532 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.

Key Features

  • include programmable short-circuit protection, overcurrent protection, adjustable dead-time control, under-voltage lockout (UVLO), 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 MP6532 is available in 28-pin, 9.7mm × 6.4mm TSSOP and 4mm x 4mm QFN packages with an exposed thermal pad.

MP6532 5V to 60V, Three-Phase Brushless DC Motor Pre-Driver DESCRIPTION The MP6532 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 MP6532 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 highside gate driver voltage even when an output is operated at 100% duty cycle Internal protection features include programmable short-circuit protection, overcurrent protection, adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown.
