Driver IC for Bipolar Stepper and DC Motors

TLE 8444SL IS A PROTECTED QUAD half-bridge IC developed for automotive and industrial motion control applications. It is a monolithic die based on Infineon’s smart mixed technology.This product can be used to drive DC motors in forward (cw), reverse (ccw), brake and high-impedance modes. It also allows stepper motors to be driven in no-current, negative/positive output current modes. These modes can be easily achieved by connecting the device to a microcontroller via a standard parallel interface.The PG-SSOP-24-7 package saves PCB board space and costs. Integrated short circuit and over temperature protection as well as built-in diagnosis features such as over- and under voltage lockout and open load detection improve system reliability and performance.

Features:

• 4 Half-Bridge Power Outputs
