VN1160-E

Overview

The VN1160-E is a smart power solution designed for automotive body applications, manufactured by STMicroelectronics. It integrates six linear voltage regulators and a 2 A high-side driver within a single monolithic device. The integrated regulators provide outputs of 8.5 V at 200 mA, 5.0 V at 300 mA, 3.3 V at 250 mA, 1.8 V at 350 mA, and two standby outputs of 3.3 V and 1.8 V at 100 mA each. The device operates down to a 4.5 V battery level and includes features such as reset functions, load dump protection, thermal shutdown, and overcurrent limitation.

Feature Summary

• Integrates multiple regulated outputs with a dedicated high-side driver for simplified system design
• Includes comprehensive protection mechanisms against overtemperature, overcurrent, and load dump events
• Features low standby current capabilities and CMOS-compatible control inputs

Applications

• Automotive body electronics systems
• Car radio and infotainment power management
• Multi-rail voltage distribution in vehicle interiors

Procurement Notes
