data sheet 1 v1.2 2008-02-04 1-a dc motor driver for servo driver applications tle 4206-2g pg-dso-14-22 overview features ? optimized for headlight beam control applications delivers up to 0.8 a continuous 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 enhanced power packages range low-voltage detection with hysteresis green product (rohs compliant) aec qualified type ordering code package tle 4206-2g on request pg-dso-14-22 description the tle 4206-2g is a protected h-bridge driver designed specifically for automotive headlight beam control and industrial servo co ntrol applications. the part is built using infineons 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 resistors. 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 4206-2g stops the motor immediately (brake condition).
tle 4206-2g data sheet 2 v1.2 2008-02-04 furthermore the built in features like ov er- and undervoltage-lockout, short-circuit- protection and over-temperat ure-protection will open a wide range of automotive- and industrial applications. the tle 4206-2g is a design-version of the tle 4206. in the tle 4206-2g, the current peak blanking pin is disconnected. a hyster esis is introduced at the lower range threshold. this allows reliable de-activation of the device by pulling the range input to gnd also under critical application conditions. aep02261 cpb 10 9 1 2 3 4 5 6 7 v 14 13 12 11 8 out1 gnd hyst fb out2 gnd range ref gnd gnd gnd gnd s pg-dso-14-22 n.c. figure 1 pin configuration (top view) pin definitions and functions pin no. pg-dso-14-23 symbol function 1 fb feedback input 2 hyst hysteresis i/o 3, 4, 5, 10, 11, 12 gnd ground 6 out1 power output 1 7 n.c. not connected 8 v s power supply voltage 9 out2 power output 2 13 range range input 14 ref reference input ? n.c. not connected
