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 1.
2 Description The TLE 4209 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 device is available in a P-DIP-8-4 package.

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.
