DC Motor Driver for Servo Driver Applications
TLE 4209
1 Overview
1.1 Features
• Optimized for headlight beam control applications
• Delivers up to 0.8 A
• Low saturation voltage;
typ. 1.2 V total @ 25 °C; 0.4 A
• Output protected against short circuit
• Overtemperature protection with hysteresis
• Over- and undervoltage lockout
• No crossover current
• Internal clamp diodes
1.2 Description
The TLE 4209 is a fully protected H-Bridge Driver designed specifically for automotive
headlight beam control and industrial servo control applications.
The part is built using Infineons bipolar high voltage power technology DOPL.
The device is available in a P-DIP-8-4 package.
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 4209 stops the motor immediately (brake condition).
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.
