TMC6140-LA- Low voltage BLDC motor driver 5 to 30V, for external N-channel MOSFETs, integrated lowside chargepump for low RDSon at low battery voltage

Part Number: TMC6140-LA

Package: QFN-36

Type: Motor Drivers

Description: Motor Driver - 3-Phase MOSFET gate driver for PMSM servo or BLDC motors

Product Overviews

TMC6140-LA 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 allow easy current sensing and enhanced commutation of the motor. A switching regulator (3.3 V, 0.5 A, internal Schottky diode for up to 100mA) generates enough power for the IOs and the micro controller.
