TLE4206

The TLE4206 has 10 features.The first one is Optimized for headlight beam control applications.The second one is Current-peak-blanking (no electrolytic capacitor at VS).The third one is Delivers up to 0.8 A continuous.The fourth one is Low saturation voltage; typ.1.2 V total @ 25 °C; 0.4 A.The fifth one is Output protected against short circuit.The sixth one is Overtemperature protection with hysteresis. The seventh one is Over- and undervoltage lockout.The eighth one is No crossover current.The ninth one is Internal clamp diodes.The tenth one is Enhanced power packages.

The TLE4206 is a fully protected H-Bridge Driver designed specifically for automotive headlight beam control and industrial servo control applications.The part is built using the Siemens bipolar high voltage power technology DOPL.The standard enhanced power P-DSO-14 package meets the application requirements and saves PCB-board space and costs. A P-DIP-16 package is also available.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 TLE4206 stops the motor immediately (brake condition).The "programable current-peak-blanking" disables the servo-loop during the VS voltage drop caused by the stall current spike. So there is no need of an electrolytic blocking capacitor at the VS-terminal.Furthermore the built in features like over- and undervoltage-lockout, short-circuitprotection and over-temperature-protection will open a wide range of automotive- and industrial applications.
