1-A Quad-HBD (Quad-Half-Bridge Driver) TLE
Overview
Features Driver for up to 3 motors Delivers up to 0.8 A continuous Optimized for DC motor management applications Very low current consumption in stand-by (Inhibit) mode Low saturation voltage; typ.1.2 V total @ °C; 0.4 Output protected against short circuit Error flag diagnosis Overvoltage lockout and diagnosis Undervoltage lockout CMOS/TTL compatible inputs with hysteresis No crossover current Internal clamp diodes Overtemperature protection with hysteresis and diagnosis Enhanced power P-DSO-Package
Type Ordering Code Package TLE 4208 G Q67007-A9335 P-DSO-28-18
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.
