MP6531A

5V - 60V, Three-Phase, Brushless,

DC Motor Pre-Driver

DESCRIPTION

FEATURES

The MP6531A is a gate driver IC designed for

three-phase, brushless, DC motor driver

applications. The MP6531A is capable of

driving three half-bridges consisting of six N-

channel power MOSFETs up to 60V.



Wide 5V to 60V Input Voltage Range

Bootstrap Gate Driver with Trickle-Charge

Circuit Supports 100% Duty Cycle

Operation

Low-Power Sleep Mode for Battery-

Powered Applications

Programmable Over-Current Protection of

the External MOSFETs

Adjustable Dead-Time Control to Prevent

Shoot-Through



The MP6531A uses a bootstrap capacitor to

generate a supply voltage for the high-side

MOSFET driver. An internal trickle-charge

circuit maintains a sufficient gate driver voltage

at 100% duty cycle.



Thermal Shutdown and UVLO Protection

Fault Indication Output

Internal safety features include programmable

over-current protection (OCP), adjustable dead-

time control, under-voltage lockout (UVLO), and

thermal shutdown.

Surface-Mounted

APPLICATIONS

The MP6531A is available in 28-pin TSSOP-EP

(9.7mmx6.4mm) and QFN-28 (4mmx4mm)

packages with exposed thermal pads on the

back.
