描述 Description

The MP6533 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 MP6533 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 MP6533 is available in a 28-pin 9.7mmx6.4mm TSSOP with an exposed thermal pad.
