Description

The TLE7235G is an eight channel high-side and low-side power switch in PG-DSO-20-45 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 TLE7235G 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 power transistors are built by N-channel power MOSFETs. The device is monolithically integrated in

Smart Power Technology.
