BTG7050-1EPL | 12 V | 50 mΩ | 3 A | adjustable current limitation up to 8.86 A | 1 channel smart high-side power switch | analog current sense, digital diagnostic

Overview

The BTG7050-1EPL, as part of the PROFET™ Load Guard family, is a single channel smart high-side power switch, providing protection functions and enhanced diagnostic capabilities. It is equipped with adjustable overcurrent limitation to offer high reliability for protecting the system: In case of a short circuit to ground, the PCB traces, connectors, as well as loads, can be protected. Furthermore, the BTG7050-1EPL has a capacitive load switching mode implemented to charge big capacitive loads and to reduce current peaks during switch on of capacitors. By these features, the device addresses different use cases for intelligent power distribution (load supply protection, wire protection and power supply protection) and a broad range of applications.

Summary of Features

Switch ON capability during inverse current condition (InverseON)
Capacitive load switching mode to charge big capacitive loads in safe operation area
Automotive qualified in accordance with AEC Q100 Grade1 and ISO 26262-ready documentation available for registered Infineon partners
Diagnostic: Proportional load current sense, open load in ON and OFF state and short circuit to ground and battery
Protection: Adjustable overcurrent limitation via external resistor and absolute and dynamic temperature protection with restart contro
