MP6537
100V, Three-Phase, BLDC Motor
Pre-Driver with PWM & Enable Inputs
DESCRIPTION
FEATURES
The MP6537 is a gate driver IC designed for
three-phase, brushless DC motor driver
applications. The MP6537 is capable of driving
three half-bridges consisting of six N-channel
power MOSFETs up to 100V.
Supports 100V Operation
120V VBST Maximum Voltage
Internal LDO Supports External NPN for
High-Current Drive Requirements
Integrated Current-Sense Amplifier
Low-Power Sleep Mode for Battery-
powered Applications
Programmable Over-Current Protection
(OCP) of External MOSFETs
Adjustable Dead-Time Control to Prevent
Shoot-Through
Thermal Shutdown and Under-Voltage
Lockout (UVLO) Protection
Fault Indication Output
Available in a Thermally Enhanced Surface-
Mounted QFN-28 (4mmx5mm) Package
The MP6537 uses a bootstrap capacitor to
generate a supply voltage for the high-side
MOSFET driver. An internal charge pump
maintains the high-side gate driver if the output
is held high for an extended period of time.
Full protection features include programmable
over-current protection (OCP), adjustable dead-
time control, under-voltage lockout (UVLO), and
thermal shutdown.
The MP6537 is available in a QFN-28
(4mmx5mm) package with an exposed thermal
pad.
APPLICATIONS
Three-Phase Brushless DC Motors and
Permanent Magnet Synchronous Motors
