MPQ6532 Three-Phase Brushless DC Motor Pre-Drivers

Monolithic Power Systems (MPS) MPQ6532 Three-Phase Brushless DC Motor Pre-Drivers are IC-designed drivers capable of driving three half-bridges, with six N-channel power MOSFETs. These motor pre-drivers operate in a wide input voltage range of 5V to 60V and a temperature range of -40°C to 125°C. The MPQ6532 pre-drivers include built-in hall sensor inputs and 120° communication logic and integrate a regulated charge pump to generate gate drive power. These drivers consist of internal safety features like configurable short-circuit protection (SCP), overcurrent protection (OCP), adjustable dead-time (DT) control, under-voltage lockout (UVLO), and thermal shutdown. The MPQ6532 pre-drivers include an internal trickle-charge circuit to maintain sufficient HS-FET driver voltage even when the output is at 100% duty cycle. Typical applications are three-phase brushless DC (BLDC) motors and permanent magnet synchronous motors (PMSMs) and automotive actuators, pumps, and fans.
