TLE4209

        The TLE4209 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 TLE4209 is available in a P-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 4209 stops the motor immediately (brake condition).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.
       TLE4209 has eight unique features: The first one is it is optimized for headlight beam control applications. The second one is delivers which is up to 0.8 A. The third one is low saturation voltage which is typ. 1.2 V total @25 °C and 0.4 A. The forth one is output protected against short circuit. The fifth one is overtemperature protection with hysteresis. The sixth one is over- and undervoltage lockout. The seventh one is no crossover current. The eighth one is internal clamp diodes.
      There are some absolute maximum ratings about TLE4209. Supply votlage (Vs) is -0.3 V min and 45 V max. Logic input voltages(FB,REF,RANGE,HYST)(V1) are -0.3 V min and 20 V max. Output current (diode)(T_out) is -1 A min and 1 A max. Input current(FB,REF,RANGE,HYST)(I_in) is -6 mA min and 6 mA max when t is less than 2 ms and t/T is less than 0.1. Junction temperature (Tj) is -40 min and 150 max . Storage temperature (Tstg0 is -50 min and 150.  Operating range: Supply votlage (Vs) is 8 V min and 18 V max after Vs rising above Vuv on. Supply voltage increasing (Vs) is -0.3 V min and Vuv on V max when outputs in tristate. Supply voltage decreasing (Vs) is -0.3 V min and Vuvon V max when outputs in tristate. Output current (I_out1-2) is -0.8 A min and 0.8 A max . Input current (FB, REF) (I_IN) is -50 mA min and 500 mA max. Junction temperature (Tj) is 40°C min and  150 °C max.
