描述 Description

The TLE 4206G is a protected H-Bridge Driver designed specifically for automotive headlight beam control and industrial servo control applications. The part is built using the Siemens 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. Moreover the package is RoHS compliant. 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 4206 stops the motor immediately (brake condition). TLE 4206G Data Sheet 2 V1.2 2008-02-04 The “programable current-peak-blanking” disables the servo-loop during the VS voltage drop caused by the stall current spike. So there is no need of an electrolytic blocking capacitor at the VS-terminal. Furthermore the built in features like over- and undervoltage-lockout, short-circuit-protection and over-temperature-protection will open a wide range of automotive- and industrial applications.
