Functional Description
General
The TLE 6363 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 6363 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
CMOS control circuitry to be integrated with DMOS power devices on the same
monolithic circuitry.
The very small P-DSO-14-2 SMD packages meet the application requirements.
