TLE8444SL数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

The TLE 8444SL is a protected Quad-Half-Bridge-IC targeted towards automotive and industrial motion control applications. It is a monolithic die based on Infineon’s 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 Stepper- Motors 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. The PG-SSOP-24-7 package is advantageous as it saves PCB-board space and costs. The integrated short circuit and over-temperature protection as well as it’s built-in diagnosis features such as over- and under voltage-lockout and open load detection improves system reliability and performance.
