DESCRIPTION

The L9925 is a dual full bridge driver for stepper motor applications. Realized in BCD (Bipolar, CMOS & DOS) techology, logic circuits, precise linear blocks and power transistors are combined to optimize circuit performance and minimize off chip components. Schmitt triggers are used for all input stages and are fully compatible with 5V CMOS logic levels. When both enable signals are low, the IC is commanded to a low quiescent current state and will draw less than 200µA from the battery.
