The SPIDER - TLE 7232G is an eight channel low-side relay switch (1.2 Ω per channel)
in P-DSO-24-3 package providing embedded protective functions. The 16 bit serial
peripheral interface (SPI) is utilized for control and diagnosis of the device and the loads.
The SPI interface provides daisy-chain capability in order to assemble multiple devices
in one SPI chain by using the same number of micro-controller pins.
The SPIDER - TLE 7232G is equipped with one input pin that can be individually routed
to the output control of each channel thus offering complete flexibility in design and PCB-
layout. The input mapping as well as the boolean operation between input signal an
output control signal is configured via SPI.
The device provides full diagnosis of the load, which is open load, short to GND as well
as short circuit to
diagnosis flags indicate latched fault conditions that may have occurred.
Each output stage is protected against short circuit. In case of over load, the current of
the affected channel is limited. There is a temperature sensor available for each channel
to protect the device in case of over temperature. The shut down behavior in case of over
load or over temperature can be configured via SPI for each channel individually.
