Description
The TLE 4206-4G is a protected H-Bridge Driver designed specifically for automotive headlight beam control
applications with DC-brush motor loads. The part is built using Infineonâs 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.
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 case of fault
conditions, like short circuit to GND, short circuit to supply-voltage, and broken wire, the TLE 4206-4G stops the
motor immediately and enters active braking (brake high). The device also incorporates integrated features like
over- and under voltage-lockout, short-circuit-protection and over-temperature-protection.
The TLE 4206-4G is a derivate of the TLE 4206-2G. The Range pin not only offers short circuit protection at the
reference potentiometer but also determines the potentiometerâs voltage range of operation. The TLE 4206-4G
considers a smaller window of operation by way of increasing the lower Range Switch off and on thresholds to
serve a larger variety of reference potentiometer strokes.
