TLE4209G.

The Infineon Technologies TLE4209GXUMA1 is a protected H-Bridge driver specifically designed for automotive manual headlight beam control and industrial servo control applications with DC-brush motor loads. Built using bipolar high voltage power technology, this component operates within an 8V to 18V range and can deliver up to 0.7A of continuous current. Its low saturation voltage is typically 1.6V total at 0.7A and 25°C.

The TLE4209G features built-in protection against short circuits to GND, short circuits to supply voltage, and broken wires, causing the motor to stop immediately in a brake condition. Additional protective features include over- and under-voltage lockout, short-circuit protection, and over-temperature protection. The standard enhanced power PG-DSO-14 package is lead- and halogen-free, saving PCB space and costs.

Servo-loop parameters such as hysteresis, deadband, and angle amplification are programmable with external resistors. An internal window-comparator controls the input line. This AEC-qualified component is optimized for manual headlight beam control and suitable for applications with small servo motors, such as vertical light leveling.
