TLE4206G

1-A DC Motor Driver for Servo Driver Applications TLE 4206G 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 Green Product (RoHS compliant) AEC Qualified PG-DSO-14-22 Type TLE 4206G Description Ordering Code on request Package PG-DSO-14-22 The TLE 4206G 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 PG-DSO-14-22 package meets the application requirements and saves PCB-board space and costs. Moreover the package is RoHS compliant. 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). Data Sheet 1 V1.1 2007-08-10 TLE 4206G 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.
