TLE8082ES | TLE8082ES supports OBDII-compliant EURO5/BHARATVI 2-/3-wheeler combustion engine systems with the focus on Electronic Fuel Injection(EFI) technologies

Overview

It is protected against overtemperature and overcurrent and provides diagnostic features for each integrate power stage. The TLE8082ES integrates a pre-regulator for external FETs, a sensor supply, a communication supply for on-board transceivers, an SPI interface and four power stages to drive different load types used in engine management systems.
The IC is a compact and cost optimized solution to meet modern emission standards and regulations of engine management systems.
