MP6539B - Three-Phase BLDC Motor Pre-Driver

Description

The MP6539B is a gate driver IC designed for three-phase, brushless DC motor driver applications.

The MP6539B is capable of driving three half-bridges consisting of six Nchannel power MOSFETs up to 100V.

Features

  • include shoot-through protection, adjustable dead-time control, undervoltage lockout (UVLO), and thermal shutdown. The MP6539B is similar to the MP6539. It does not implement auto bootstrap charging, does not include over-current protection, and is powered only from the VDD pin (VIN and LDO have been removed). The MP6539B is available in TSSOP-28 (9.7mmx6.4mm) and QFN-28 (4mmx5mm) packages with an exposed thermal pad.

MP6539B 100V, Three-Phase BLDC Motor Pre-Driver DESCRIPTION The MP6539B is a gate driver IC designed for three-phase, brushless DC motor driver applications. The MP6539B is capable of driving three half-bridges consisting of six Nchannel power MOSFETs up to 100V. The MP6539B uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate drive if the output is held high for an extended period of time. Internal safety features include shoot-through protection, adjustable dead-time control, undervoltage lockout (UVLO), and thermal shutdown. The MP6539B is similar to the MP6539.
