Description

The TLE 4206 is a fully 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 P-DSO-14 package meets the application requirements

and saves PCB-board space and costs. A P-DIP-16 package is also available.

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).

The “programable current-peak-blanking” disables the servo-loop during the

V

drop caused by the stall current spike. So there is no need of an electrolytic blocking

capacitor at the

V

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.
