Description
The TLE7235SE 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 TLE7235SE 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.
