Description
The SPIDER - TLE 7240SL is a eight channel low-side switch in PG-SSOP-24-7 package providing embedded
protective functions.
It is especially designed as relay driver in automotive applications.
A serial peripheral interface (SPI) is utilized for control and diagnosis of the device and the load.
For direct control and PWM there are four input pins available.
The device is monolithically integrated. The power transistors are built by N-channel MOSFETs.
