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.
