TLE 7201R
Power ASSP for
Automotive Door-Zone Modules
The TLE 7201R is an Application Specific Standard
Product (ASSP) for automotive door-module appli-
cations. 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 up to four 5 W lamps,
e.g for turn signal, courtesy/warning or control
panel illumination. It is designed as a monolithic
circuit, using 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.
