MP6539B

100V, Three-Phase BLDC Motor Pre-Driver

DESCRIPTION

FEATURES

The MP6539B is a gate driver IC designed for

three-phase, brushless DC motor driver

applications. The MP6539B is capable of

driving three half-bridges consisting of six N-

channel power MOSFETs up to 100V.



Supports 100V Operation

120V V_BSTMaximum Voltage

Integrated Current-Sense Amplifier

Low-Power Sleep Mode for Battery-

Powered Applications



Adjustable Dead-Time Control to Prevent

Shoot-Through

Thermal Shutdown and Under-Voltage

Lockout (UVLO) Protection

Fault Indication Output

Available in Thermally Enhanced, Surface-

Mounted TSSOP and QFN Packages

The MP6539B uses a bootstrap capacitor to

generate a supply voltage for the high-side

MOSFET driver. An internal charge pump

maintains the high-side gate drive if the output

is held high for an extended period of time.



Internal safety features include shoot-through

protection, adjustable dead-time control, under-

voltage lockout (UVLO), and thermal shutdown.

APPLICATIONS

The MP6539B is similar to the MP6539. It does

not implement auto bootstrap charging, does

not include over-current protection, and is

powered only from the VDD pin (VIN and LDO

have been removed).



Three-Phase, Brushless DC Motors and

Permanent Magnet Synchronous Motors

Power Drills
