TLE8718SA: Highly Flexible 18-Channel, Low-Side Switch Optimized for Powertrain Applications

Infineon TLE8718SA

Infineon's Flex multi-channel, low-side switches for powertrain, safety and industrial applications are specially designed to drive a wide range of loads. This all-round family concept combines full scalability (from two to eighteen channels) with leading-edge technology. All Flex multi-channel switches are equipped with proven, embedded protection functions and enhanced diagnostics for a wide range of platforms.

Infineon - TLE8718SA

TLE8718SA is the latest and most advanced addition to the Flex multi-channel switch family. It can drive a wide variety of inductive and resistive loads such as injectors, valves, relays, LEDs and O2 heaters. The high speed Micro Second Channel (MSC) interface reduces the number of control pins required, thus ensuring that the 18-channel device is ultra compact and has a high power density.

TLE8718SA is equipped with highly sophisticated protection and diagnosis features and tailored to the requirements of powertrain applications. Infineon's zero-defect excellence program for the automotive industry ensures the highest quality every time. Features
