MP6538

100V, Three-Phase BLDC Motor Pre-Driver with Hall Signal Interface

Datasheet

Description

The MP6538 is a gate driver IC designed for three-phase, brushless DC motor driver applications. The MP6538 is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 100V.

The MP6538 uses bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate driver if the output is held high for an extended period of time.

Full protection features include programmable over-current protection (OCP), adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown.
The MP6538 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 MP6538 is available in a QFN-28 (4mmx5mm) package with an exposed thermal pad.

Evaluation Tools

EV6538-V-00A Evaluation Kit 8V to 100V, Three-Phase Brushless DC Motor Pre-Driver Evaluation Board

The EV6538-V-00A is an evaluation board for the MP6538, a three-phase BLDC motor pre-driver.

It operates from a supply voltage of up to 100V. 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 and the driving control signals are generated by the external controller, such as MCU, FPGA, etc.
