描述 Description

The TLE4209G is a protected H-Bridge Driver designed specifically for automotive manual headlight beam control and industrial servo control applications with DC-brush motor loads. The part is built using the bipolar high voltage power technology DOPL. The standard enhanced power PG-DSO-14-22 package meets the application requirements and saves PCBboard space and costs. The package is lead- and halogen-free. The servo-loop-parameter pos.- and neg. Hysteresis, pos.- and neg. deadband and angle-amplification are programmable with external resistors. 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 TLE4209G stops the motor immediately (brake condition). Furthermore the built in features like over- and under voltage-lockout, short-circuit-protection and overtemperature- protection will open a wide range of automotive- and industrial applications.
