DESCRIPTION
The TMC6200 is a high-power gate-driverfor PMSM servo or BLDC motors. Using six external MOSFETs and two or three sense resistors, it integrates the full high voltage part of a PMSM drive system for 12V, 24V or 48V, including in-line current sense amplifiers with programmable
amplification. It can drive a wide range of motors from Watt to Kilowatt.
Software controlled drive strength allows in-system EME optimization. Programmable safety features like short detection and overtemperature thresholds together with an SPI interface for diagnostics allow robust and reliable designs. With the TMC6200, a minimum number of external components is required to build a rugged drive with full protection and
diagnostics.

APPLICATION EXAMPLES: PMSM AND BLDC MOTORS
The TMC6200 scores with integration of the complete high-voltage part for FOC controlled PMSM drivers. On the control side, it mates with sophisticated FOC TMC467x and TMC867x family controller chips, or with any microcontroller. Its versatile interface matches simple BLDC drives with minimum requirements on the μC PWM, as well as advanced PMSM control algorithms. The small form factor and easy-to-use package of the TMC6200 keeps costs down and allows for miniaturized layouts. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products. High integration and reliability deliver cost savings in related systems such as power supplies and cooling.
A CPU with internal BLDC or sine wave PWM unit drives the gate control lines based on encoder or hall sensor feedback. The current sensor outputs become sampled by the μC integrated ADC. Use of SPI is not required unless more sophisticated diagnostics is desired.
When using one of the TRINAMIC FOC controllers, the CPU is completely offloaded from time-intensive regulation loop tasks,
and software design shrinks to initialization and target parameter setting. The TMC6200 optimally complements a TMC467x family controller.
The TMC6200-EVAL is part of TRINAMICs universal evaluation board system which provides a convenient handling of the hardware as well as a user-friendly software tool for evaluation. The TMC6200 evaluation board system consists of three parts:
LANDUNGSBRüCKE (base board),
ESELSBRüCKE (connector board including
several test points), and TMC6200-EVAL,
plus a TMC4671-EVAL FOC controller.

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.
