LIN Engineering, represented in Australia by Switches Plus Components , is offering complimentary samples of Trinamic integrated circuits. Samples of TMC 222, TMC 428 and TMC 246 are available.
The TMC 222 integrates an I2C interface, a positioning controller and an 800mA, 2-phase step motor driver in a single chip. The driver features a resolution of up to 16μ steps and integrates high performance current regulation. The TMC222 is ideal for a wide range of distributed single axis positioning applications.
The TMC 428 is a high performance step motor control IC. It controls one to three 2-phase step motors and autonomously handles all real time critical motion control tasks including ramping and microstep sequencing. All target parameters such as position, velocity and acceleration can be changed on-the-fly.
The TMC 246 is a dual full bridge driver IC for bipolar step motor control applications. The TMC 246 features StallGuard sensor less stall detection. StallGuard detects a stall in the motor without the use of an encoder. Its ability to predict an overload makes the TMC 246 a suitable choice for drives where high reliability is desired.
