2.0, 6/2007 Programmable H-Bridge Power IC 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 diagn
