Features

The TMC236 / TMC236A (1) is a dual full bridge driver IC for bipolar stepper motor control

applications. It is realized in a HVCMOS technology combined with Low-RDS-ON high efficiency

MOSFETs (pat. pend.). It allows driving a coil current of up to 1500mA even at high environment

temperatures. Its low current consumption and high efficiency together with the miniature package

make it a perfect solution for embedded motion control and for battery powered devices. The low

power dissipation makes the TMC236 an optimum choice for drives, where a high reliability is desired.

Internal DACs allow microstepping as well as smart current control. The device can be controlled by a

serial interface (SPI™ⁱ) or by analog / digital input signals. Short circuit, temperature, undervoltage and

overvoltage protection are integrated.

Control via SPI with easy-to-use 12 bit protocol or external analog / digital signals

Short circuit, overvoltage and over temperature protection integrated

Status flags for overcurrent, open load, over temperature, temperature pre-warning, undervoltage

Integrated 4 bit DACs allow up to 16 times microstepping via SPI (can be expanded to 64

microsteps)

Any resolution via analog control

Mixed decay feature for smooth motor operation

Slope control user programmable to reduce electromagnetic emissions

Chopper frequency programmable via a single capacitor or external clock

Current control allows cool motor and driver operation

Internal open load detector

7V to 34V motor supply voltage (A-type)

Up to 1500mA output current and more than 800mA at 105°C

3.3V or 5V operation for digital part

Low power dissipation via low RDS-ON power stage

Standby and shutdown mode available

(1) The term TMC236 in this datasheet always refers to the TMC236A and the TMC236. The major

differences in the older TMC236 are explicitly marked with “non-A-type”. The TMC236A brings a

number of enhancements and is fully backward compatible to the TMC236
