Description
The TLE8108EM is an 8-Channel Low Side Switch in PG-SSOP-24 package providing embedded protective
functions.
It is especially designed as relay driver for powertrain automotive applications.
A serial peripheral interface (SPI) is implemented for control and diagnosis of the device and the load.
Four configurable direct inputs are available to control the outputs in PWM.
The device is monolithically integrated. The internal switches are power n-MOSFETs.
