MP6534 - Brushless DC Motor Pre-Driver

Description

The MP6534 is a gate driver IC designed for three-phase brushless DC motor driver applications.

It is capable of driving three half bridges consisting of 6 N-channel power MOSFETs up to 55V.

The MP6534 includes a 500mA buck regulator to generate local power for microcontrollers or other circuitry.

Features

  • include programmable short-circuit protection, overcurrent protection, adjustable dead-time control, undervoltage lockout, and thermal shutdown. The MP6534 is available in a 40-contact QFN (5mm x 5mm) package with an exposed thermal pad.

The Future of Analog IC Technology MP6534 5V to 55V, Three-Phase, Brushless DC Motor Pre-Driver with Buck Regulator DESCRIPTION The MP6534 is a gate driver IC designed for three-phase brushless DC motor driver applications. It is capable of driving three half bridges consisting of 6 N-channel power MOSFETs up to 55V. The MP6534 includes a 500mA buck regulator to generate local power for microcontrollers or other circuitry. The MP6534 integrates a regulated charge pump to generate gate drive power, and uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal trickle-charge circuit maintains sufficient high-side gate driver voltage even when an output is operated at 100% duty cycle.
