Advance Information

Programmable H-Bridge

Power IC

33899

The 33899 is designed to drive a DC motor in both forward and

reverse shaft rotation under pulse-width modulation (PWM) control of

speed and torque. A current mirror output provides an analog

feedback signal proportional to the load current. A serial peripheral

interface (SPI) is used to select slew rate control, current

compensation limits and to read diagnostic status (faults) of the H-

Bridge drive circuits. SPI diagnostic reporting includes open circuit,

short-circuit to VIGNP, short-circuit to ground, die temperature range,

and under-voltage on VIGNP.
