MP6546

22V, 3A, Peak, 3-Phase BLDC Driver

with 1MHz I²C Interface

DESCRIPTION

FEATURES

The MP6546 is a 3-phase brushless DC (BLDC)

motor driver for gimbal applications. It has three

half-bridge power stages, pre-drivers, field-

oriented 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

•

3.5V to 22V Operating Supply Voltage

Three Half-Bridge Drivers

Up to 1MHz Fast-Mode Plus for I²C

Configurable Slave Addresses

Supports Different Angle Sensor Inputs:

o Linear Hall Sensor Input through HA/HB

o Magnetic Angle Sensor through

SPI/SSC Interface

Integrated 12-Bit Analog-to-Digital

Converter (ADC) for Hall Sensor

D-Axis and Q-Axis Voltage Loop with Field-

Oriented Control (FOC)

Standby Mode to Save Quiescent Current

Under-Voltage Lockout (UVLO), Thermal

Shutdown (TSD), Over-Current Protection

(OCP), Short-Circuit Protection (SCP), and

Over-Voltage Protection (OVP)

One-Time Programmable (OTP) Memory

Available in a QFN-20 (3mmx4mm)

Package

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), over-

current protection (OCP), short-circuit protection

(SCP), and over-voltage protection (OVP).

•

The MP6546 is available in a QFN-20

(3mmx4mm) package with an exposed thermal

pad.

APPLICATIONS

•

Gimbals

Three-Phase Brushless DC (BLDC) Motors
