DC Motor Driver for Servo Driver Applications TLE 4209A 1Overview 1.1 Features Optimized for headlight beam control applications Delivers up to 0.8 A Low saturation voltage typ. 1.2 V total 25 C 0.4 A PG-DIP-8-4 Output protected against short circuit Overtemperature protection with hysteresis Over- and undervoltage lockout No crossover current Internal clamp diodes Green Product (RoHS compliant) AEC Qualified 1.2 Description The TLE 4209A is a fully protected H-Bridge Driver designed specifically for automotive headlight beam control and industrial servo control applications. The part is built using Infineons bipolar high voltage power technology DOPL. The device is available in a PG-DIP-8-4 package. The servo-loop-parameter pos.- and neg. Hysteresis, pos.- and neg. deadband and angle-amplification are programmable with external resitors. An internal window-comparator controls the input line. In the case of a fault condition, like short circuit to GND, short circuit to supply-voltage, and broken wire, the TLE 4209A stops the motor immediately (brake condition). Furthermore the built in features like over- and undervoltage-lockout, short-circuit- protection and over-temperature-protection will open a wide range of automotive- and industrial applications.
