Introduction

NSMB05S50M1 is a highly integrated, high-reliability three-phase BLDC motor driver, primarily designed for low-power fan motor applications. The module incorporates 6 fast-recovery power MOSFETs and 3 half-bridge high-voltage gate drivers. Built-in undervoltage protection provides excellent protection and fail-safe operation. With an independent negative DC terminal per phase, phase currents can be sensed individually. The design features high isolation, good thermal conductivity, and low EMI in an extremely compact package, making it easy to use — particularly well-suited for motor-integrated applications and space-constrained installations.
