1-A DC Motor Driver for Servo Driver Applications TLE 4206-2G Overview Features • • • • • • • • • • • • Optimized for headlight beam control applications 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 Range low-voltage detection with hysteresis Green Product (RoHS compliant) AEC Qualified PG-DSO-14-22 Type Ordering Code Package TLE 4206-2G on request PG-DSO-14-22 Description The TLE 4206-2G is a 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 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 resistors. An internal windowcomparator 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 4206-2G stops the motor immediately (brake condition). Data Sheet 1 V1.2 2008-02-04 TLE 4206-2G 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. The TLE 4206-2G is a design-version of the TLE 4206. In the TLE 4206-2G, the current peak blanking Pin is disconnected. A hysteresis is introduced at the lower RANGE threshold. This allows reliable de-activation of the device by pulling the RANGE input to GND also under critical application conditions. PG-DSO-14-22 FB HYST GND GND GND OUT1 n.c.
