1 Principles of Operation
The TMC6200 is a MOSFET gate driver for three phase PMSM and BLDC motors. Ideally suited for
applications in the range of 12V to 48V, it supports motor power ratings from 1 Watt to 1kW. It
complements with TRINAMICs TMC467x & TMC867x families of three phase motor controller ICs.
Internal break-before-make timing is provided for the ease-of-use in combination with simple
microcontrollers for PWM generation. Integrated current sense amplifiers eliminate costly sense
amplifiers required for FOC controllers (recommended use for applications up to 10A, use external
precision amplifiers for higher current with low sense resistor values), while bringing the benefit of
in-line current sensing. A complete set of protection and diagnostic functions makes the power stage
more rugged than a discrete setup.
THE TMC6200 OFFERS TWO BASIC MODES OF OPERATION:
MODE 1: Stand-alone driver with pin configuration
Enable this mode by tying low pin SPE. The interface pins allow a number of different settings for
BBM generation and sense amplifier amplification control.
MODE 2: SPI controlled
This mode allows detailed control over the protection, diagnostic and control features, e.g. for tuning
overcurrent detection. Enable this mode by tying high pin SPE.
