The TLE 8201R is an Application Specific Standard Product for automotive door-module
applications. It includes all the power stages necessary to drive the loads in a typical front
door application, i.e. central lock, deadlock or mirror fold, mirror position, mirror defrost
and 5W or 10W lamps, e.g for turn signal, courtesy/warning or control panel illumination.
It is designed as a monolithic circuit in Infineons mixed technology SPT which combines
bipolar and CMOS control circuitry with DMOS power devices. 

Short circuit and over-temperature protection and a detailed diagnosis are in line with the
safety requirements of automotive applications. The current sense output allows to
improve the total system performance. The standard SPI interface saves microcontroller
I/O lines while still giving flexible control of the power stages and a detailed diagnosis.
