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 L9925 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 L9925 is commanded to a low quiescent current state and will draw less than 200mA from the battery.

The charge pump is integrated on chip; no external componentsare required. Full performance is maintaned for 9V <VS <16V. Extended ranges of 6V <<VS <9V and 16V <VS <40V yields full functionally but with relaxed performance. Over temperature protection and ESD protection to all pins ensures relability and reduces system integration failures.
