Motor Driver IC TLE8444SL Quad Half-Bridge Driver IC SSOP24 Surface Mount

Product Description Of TLE8444SL

TLE8444SL is a protected Quad-Half-Bridge-IC targeted towards automotive and industrial motion control applications. TLE8444SL is a monolithic die based on smart mixed technology SPT which combines bipolar and CMOS control circuitry with DMOS power devices. DC-Motors can be driven in forward (cw), reverse (ccw), brake and high impedance modes where as StepperMotors can be driven in No-Current, negative / positive output current modes. These various modes can easily be achieved via standard parallel interface of the device to a microcontroller.
