MP6543H

22V, 2A, Three-Phase Power Stage

DESCRIPTION

FEATURES

The MP6543H family of products (MP6543H,

MP6543H-A, and MP6543H-B) are three-phase

brushless DC motor drivers. They integrate three

half-bridges, consisting of six N-channel power

MOSFETs, as well as pre-drivers, gate drive

power supplies, and current-sense amplifiers.



3V to 22V Operating Supply Voltage

Three Integrated Half-Bridge Drivers

2A Continuous Output Current

MOSFET On Resistance: 110mΩ per FET

MP6543H: EN and PWM Inputs

MP6543H-A: LS and HS Inputs

MP6543H-B: Hall-Effect Sensor Inputs

Built-In 3.3V, 100mA LDO Regulator

Internal Charge Pump Supports 100% Duty

Cycle Operation

Automatic Synchronous Rectification

Under-Voltage Lockout (UVLO) and

Thermal Shutdown Protection

Over-Current Protection (OCP) with

Adjustable Threshold

The MP6543H has enable (EN) and PWM inputs

for each half-bridge. The MP6543H-A has

separate high-side (HS) and low-side (LS) inputs,

while the MP6543H-B has Hall-effect sensor

inputs. Otherwise, these three devices are

similar. References to the MP6543H in this

document apply to the MP6543H-A and

MP6543H-B, unless otherwise noted.



The MP6543H delivers up to 2A of continuous

current (depending on thermal and PCB

conditions) with an adjustable over-current

protection (OCP) threshold. It uses an internal

charge pump to generate the gate drive supply

voltage for the high-side MOSFETs, and a trickle

charge circuit to maintain a sufficient gate drive

voltage to operate at 100% duty cycle.

Integrated, Bidirectional Current-Sense

Amplifiers

Available in a QFN-24 (3mmx4mm)

Package

APPLICATIONS



3-Phase Brushless DC Motor Drivers
