Step Down Voltage Regulator with Reset TLE 6365 Features • Step down converter • Supply Over- and Under-Voltage-Lockout • Low Output voltage tolerance • Output Overvoltage Lockout • Output Under-Voltage-Reset with delay • Overtemperature Shutdown • Wide Ambient operation range -40 °C to 125 °C • Wide Supply voltage operation range • Very low current consumption • Very small PG-DSO-8 SMD package • Green Product (RoHS compliant) • AEC Qualified P/PG-DSO-8-3, -6, -7, -8, -9 Functional Description The TLE 6365 G is a power supply circuit especially designed for automotive applications. 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 TLE 6365 G contains a buck converter and a power on reset feature to start up the system The very small PG-DSO-8 SMD package meets the application requirements. It delivers a precise 5 V fully short circuit protected output voltage. Furthermore, the build-in features like under- and overvoltage lockout for supply- and output-voltage and the overtemperature shutdown feature increase the reliability of the TLE 6365 G supply system.
