The MP6535 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 55V.
It includes a 500mA buck regulator to generate local power for a microcontroller or other circuitry,
The MP6535 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, adjustable dead time protection, UVLO and thermal shutdown.
The device has three Hall-sensor 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, position, and torque.
The MP6535 is available in a 40-contact 5mmx5mm QFN with an exposed thermal pad.
