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.
