About This Product

■Summary

The MP6546 is a 3-phase brushless DC (BLDC) motor driver for gimbal applications. It features three half-bridge power stages, predrivers, field-oriented control (FOC) logic, and angle calculation. The MP6546 supports linear Hall angle input or MPS magnetic angle sensor input. MP6546 supports multi-slave mode, allowing you to connect a 3-axis gimbal to a single digital interface to reduce microcontroller (MCU) load and system cost. MP6546 can supply up to 3A load current. An internal charge pump is used to generate the gate driver supply voltage for the high-side MOSFET (HS-FET). Internal safety features include thermal shutdown, undervoltage lockout (UVLO), overcurrent protection (OCP), short circuit protection (SCP), and overvoltage protection (OVP). The MP6546 is available in a (3mm x 4mm) package with exposed pad.

■Features and benefits

・Operating power supply voltage from 3.5V to 22V ・3 half bridge drivers ・Fast-Mode Plus up to 1MHz for digital interfaces ・Configurable slave address ・Integrated 12-bit analog-to-digital converter (ADC) for Hall sensors ・D-axis and Q-axis voltage loops with field oriented control (FOC) ・Standby mode to save static current ・Low voltage lockout function (UVLO) ・Thermal shutdown (TSD) ・Overcurrent protection (OCP) ・Short circuit protection (SCP) ・Overvoltage protection (OVP) ・Memory ・Provided in QFN-20 (3mm x 4mm) package

■Supports various angle sensor inputs:

・Linear Hall sensor input through HA/HB ・Magnetic angle sensor via SPI/SSC interface

■Available product numbers

・MP6546GL-0000-Z MP6546GL-0000-P MP6546GL-xxxx-Z MP6546GL-xxxx-P ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
