DESCRIPTION The MP6546 is a 3-phase brushless DC (BLDC) motor driver for gimbal applications. It has three half-bridge power stages, pre-drivers, fieldoriented control (FOC) logic, and angle calculations. The MP6546 supports linear Hall angle inputs or an MPS magnetic angle sensor input. The MP6546 supports multi-slave mode and allows three-axis gimbals to be connected to a single I2C interface to reduce the microcontroller (MCU) load and system cost. The MP6546 can deliver up to 3A of peak current. It uses an internal charge pump to generate the gate drive supply voltage for the high-side MOSFETs (HS-FETs). Internal safety features include thermal shutdown, under-voltage lockout (UVLO), overcurrent protection (OCP), short-circuit protection (SCP), and over-voltage protection (OVP).
