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
