INTEGRATED CIRCUITS

Dedicated 3-phase gate driver for 3-Phase BLDC

TMC6140 Datasheet

IC Version V1.0 | Document Revision V1.03 • 2021-Oct-15

TMC6140 is a fully integrated universal 3-phase MOSFET gate driver for PMSM servo or BLDC motors.

External MOSFETs for up to 100 A motor current are supported. Three bottom shunt ampliﬁers al-

low easy current sensing and enhanced commutation of the motor. A switching regulator (3.3 V,

0.5 A, internal Schottky diode for up to 100 mA) generates enough power for the IOs and an exter-

nal microcontroller. Further on, it can serve as step-up converter to stabilize statically the gate

voltages of the MOSFETs. A DIAG output for further diagnostics and two diﬀerent power down

modes are available.

Features

• 3-phase motors up to 100 A

coil current (external MOSFETs)

• Voltage Range 5...30 V DC

• Gate Drive 0.5 A or 1.0 A

• 3V3 Switching Regulator (0.5 A) with

internal Schottky diode (up to 100 mA)

• Charge pump pin to utilize buck

converter for step-up converter

• 3 Bottom Shunt Ampliﬁers

• Analog programmable short detect

• 2 Low Power Modes with 0.25 mA

standby current consumption

• Diagnostics output via UART-TxD

Applications

• Industrial Drives

• Power Tools

• Robotics

• Textile Machines

• Factory Automation

• Laboratory Automation

• Pumps

• Fans

• Battery Operated Devices
