The TLE6711G/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 TLE6711G/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 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 PG-DSO-14-1 SMD packages of the TLE6711G 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 TLE6711G/GL supply system.
