Part details & applications

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 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. 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.
