Overview
The TLE8104E, produced by Infineon Technologies, is a smart quad-channel low-side power switch designed for Powertrain applications. It is equipped with a Serial Peripheral Interface (SPI) for control and diagnosis, making it highly versatile for various automotive and industrial uses. The device features four open drain DMOS output stages and is protected by embedded protection functions such as over-current, over-temperature, and overvoltage protection. It also includes active clamping circuitry for driving inductive loads and supports load status detection for short to ground, open load, and short to battery conditions.
