Multifunctional Voltage Regulator and Watchdog TLE 6711 Data Sheet 1 1.1 Overview 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 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 P-DSO-14-3 SMD package Ordering Code Q67006-A9455-A201-A7 Package P-DSO-14-3 Type TLE 6711 G 1.2 Functional Description The TLE 6711 G 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 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 Infineon’s 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 P-DSO-14-3 SMD packages meet the application requirements. Furthermore, the build-in features like under- and overvoltage lockout for boost- and Data Sheet V 2.22 1 2001-04-23 TLE 6711 Overview...
