Data Sheet, Rev. 3.4, August 2007 TLE 6711 G/GL Multifunctional Voltage Regulator and Watchdog Automotive Power Multifunctional Voltage Regulator and Watchdog TLE 6711 G TLE 6711 GL Features Step up converter (Boost Voltage) Boost Over- and Under-Voltage-Lockout Step down converter (Logic Voltage) 2% output voltage tolerance Logic Over- and Under-Voltage-Lockout Overtemperature Shutdown P/PG-DSO-14-3, -8, -9, -11, 14 Power ON/OFF reset generator Digital window watchdog System Enable Output Ambient operation temperature range -40 C to 125 C Wide Supply voltage operation range Very low current consumption Very small PG-DSO-14-1 SMD package Green Product (RoHS Compliant) AEC Qualified P/PG-DSO-20 -1, -6, -7, -9, -14, -15, -17, -18 Description The TLE 6711 G/GL is a multifunctional power supply circuit especially designed for automotive applications. It delivers a programmable step up voltage (Boost) and a precise 5 V fully short circuit protected output voltage (Buck). The TLE 6711 G/GL contains a power on reset feature to start up the system, an integrated digital window watchdog to monitor the connected microcontroller and a system enable output to indicate the microcontroller window watchdog faults. The device is based on Infineons power technology SPT which allows bipolar and CMOS control circuitry to be integrated with DMOS power devices on the same monolithic circuitry. The very small PG-DSO-14-1 SMD packages meet the application requirements. Furthermore, the build-in features like under- and overvoltage lockout for boost- and buck-voltage and the overtemperature shutdown feature increase the reliability of the TLE 6711 G/GL supply system.
