TLE4206G

1-A DC Motor Driver for Servo Driver Applications TLE 4206 Overview Features Optimized for headlight beam control applications Current-peak-blanking (no electrolytic capacitor at VS) Delivers up to 0.8 A continuous Low saturation voltage; typ.1.2 V total @ 25 °C; 0.4 A Output protected against short circuit Overtemperature protection with hysteresis Over- and undervoltage lockout No crossover current Internal clamp diodes Enhanced power packages Ordering Code Q67000-A9303 Q67006-A9299 Package P-DIP-16-5 P-DSO-14-4 P-DSO-14-4 P-DIP-16-5 Type TLE 4206 TLE 4206 G Description The TLE 4206 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 TLE 4206 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 ...
