... MTS2916A 3.0 FUNCTIONAL DESCRIPTION The circuit is designed to drive the two windings of a bipolar stepper motor and can be divided in two identi- cal channels (channel 1 and channel 2) and protection circuitry for over temperature and undervoltage. The functionality of a channel and protection circuitry is presented on next sections. ...

... FIGURE 3-4: Thermal Shutdown Output vs. Temperature Showing Hysteresis An undervoltage lockout circuit protects the MTS2916A from potential shoot-through currents when the load supply voltage is applied prior to the logic supply volt- age. The power bridge and all outputs are disabled if VLOGIC is smaller than 4V. ...
