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.
