Description

The TLE7239SL is an eight channel high-side and low-side power switch in PG-SSOP-24-5 package providing embedded protective functions. It is especially designed for standard relays and LEDs in automotive applications. The output stages incorporate two low-side, four high-side and two auto configuring high-side or low-side switches.

A serial peripheral interface (SPI) is utilized for control and diagnosis of the device and the load. For direct control, there are two input pins available.

The TLE7239SL provides a micro controller fail-safe function which is activated via a high signal at the limp home input pin. There is a power supply integrated in the device to ensure this functionality even without digital supply voltage. The integrated power supply is designed to fulfll cranking mode requirements. The power transistors are built by N-channel power MOSFETs. The device is monolithically integrated in Smart Power Technology.
