Description
The TLE 4208 is a fully protected
Quad-Half-Bridge-Driver
designed specially for
automotive and industrial motion control applications.
The part is built using the Siemens bipolar high voltage power technology DOPL.
In a cascade configuration up to three actuators (DC motors) can be connected between
the four half-bridges. These four half-bridges are configured as 2 dual-half-bridges,
which are supplied and controlled separately. Operation modes forward (cw), reverse
(ccw), brake and high impedance are invoked from a standard interface.
The standard enhanced power P-DSO-28 package meets the application requirements
and saves PCB-board space and costs.
Furthermore the built-in features like diagnosis, over- and undervoltage-lockout, short-
circuit protection, over-temperature protection and the very low quiescent current in
stand-by mode will open a wide range of automotive and industrial applications.
