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.

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.
