Product Description

The MP6532 is a gate driver IC designed for 3-phase brushless DC motor driver applications. It is capable of driving 3 half bridges consisting of 6 N-channel Power MOSFETs up to 60V.

The MP6532 uses bootstrap capacitor to generate a supply voltage of high-side MOSFET driver, and an internal trickle charge circuit maintains sufficient gate driver voltage at 100% duty cycle.

Internal safety features include programmable over-current protection, motor startup current limit, adjustable dead time control, UVLO and thermal shutdown.

The device has three Hall-element inputs. Commutation logic is determined by three Hall-element inputs spaced at 120°. The PWM, DIR, and nBRAKE inputs are used to control motor speed, direction, and brake engagement.

The MP6532 is available in a 28-contact 4mmx4mm QFN with an exposed thermal pad.

Kit details

The EVKT6532 is an evaluation board for the MP6530, a three-phase BLDC motor pre-driver.

The EVKT6532 operates from a supply voltage of up to 60V. It is configured to drive 3 half bridges consisting of 6 N-channel Power MOSFETs. The rotor position information is provided by the Hall sensors assembled in the motor. Motor speed and direction are controlled by an on-board microcontroller.
