SPI Driver for Enhanced Relay Control

SPIDER - TLE7243SL

Overview

Protection Functions

•

Short circuit

Over load

Over temperature

Electrostatic discharge (ESD)

Application

•

All types of resistive, inductive and capacitive loads

Especially designed for driving relays in automotive applications

Detailed Description

The SPIDER - TLE7243SL is a eight channel low-side relay switch designed for typical automotive relays

providing embedded protective functions. The PG-SSOP-24-7 package is used to get a footprint optimized

solution. 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.

The SPIDER - TLE7243SL is equipped with four input pins that can be individually routed to the output control of

their dedicated channels thus offering flexibility in design and PCB layout. The input multiplexer is controlled via

SPI.

There is a dedicated limp home pin LHI which provides a straightforward usage of the input pins as dedicated

driver for four outputs.

The device provides full diagnosis of the load, which is open load as well as short circuit detection. The SPI

diagnosis bits indicate latched fault conditions that may have occurred.

Each output stage is protected against short circuit. In case of over load, the affected channel switches off. There

are temperature sensors available for each channel to protect the device in case of over temperature.

The device is supplied by two power supply lines. The analog supply supports 5 V, the digital supply offers a very

wide flexibility in supply voltage ranging from 3.0 V up to 5.5 V.

The power transistors are built by N-channel vertical power MOSFETs. The inputs are ground referenced CMOS

compatible. The device is monolithically integrated in Smart Power Technology.

In terms of PCB layout improvement, all output pins are available at one side of the device. The other side bundles

the signals to the micro-controller.
