描述 Description

The TLE4208G is a protected Quad-Half-Bridge-Driver designed specially for automotive and industrial motion control applications. The part is built using Infineons 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 PG-DSO-28-24 package meets the application requirements and saves PCB-board space and costs. Moreover the package is RoHS compliant. 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.
