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.
