electronic applications containing multiple bipolar stepper
motors and / or brush DC motors. The device features an on-
board DC / DC converter to provide gate-drive voltages, as
well as level-shifting circuitry. The control logic translates the
input signals to the gate-driver circuitry while providing cross-
conduction suppression.

undervoltage threshold. If the supply voltage drops below the
undervoltage threshold, the output power stage switches to a
tri-state condition. When the supply voltage returns to a level
that is above the threshold, the power stage automatically
resumes normal operation according to the established
condition of the input control terminals.

are taken HIGH, the associated bridge’s outputs are both tri-
