MPQ6532 - Three-Phase Brushless DC Motor Pre-Driver

General Description

The MPQ6532 is a gate driver IC designed for three-phase brushless DC (BLDC) motor driver applications.

It is capable of driving three halfbridges, consisting of six N-channel power MOSFETs, up to 60V.

Key Features

  • include configurable short-circuit protection (SCP), over-current protection (OCP), adjustable dead-time (DT) control, under-voltage lockout (UVLO), and thermal shutdown. The MPQ6532 integrates 120° commutation using three Hall sensor inputs. The pulse-width modulation (PWM), DIR, and nBRAKE inputs control the motor speed, direction, and braking, respectively. The MPQ6532 is available in a QFN-28 (4mmx5mm) package with an exposed thermal pad, and is AEC-Q100 qualified. MPQ6532 5V to 60V, Three-.

DESCRIPTION The MPQ6532 is a gate driver IC designed for three-phase brushless DC (BLDC) motor driver applications. It is capable of driving three halfbridges, consisting of six N-channel power MOSFETs, up to 60V. The MPQ6532 integrates a regulated charge pump to generate gate drive power, and uses a bootstrap (BST) capacitor to generate a supply voltage for the high-side MOSFET (HS-FET) driver. An internal trickle-charge circuit maintains a sufficient HS-FET driver voltage even when the output is at 100% duty cycle. Internal safety features include configurable short-circuit protection (SCP), over-current protection (OCP), adjustable dead-time (DT) control, under-voltage lockout (UVLO), and thermal shutdown. The MPQ6532 integrates 120° commutation using three Hall sensor inputs.
