Description
TLE 4205 is an integrated power full-bridge DC-motor driver for a wide temperature
range, as required in automotive applications for example. The circuit contains two
power comparators that can be combined to a full-bridge circuit. For inductive loads
there are integrated free-wheeling diodes to + VS and ground. The outputs are short-
circuit proof up to 18 V supply voltage to ground and turn off when overtemperature
occurs. This IC is especially suitable for headlight-beam adjustment in automobiles.
