Introduction

SPIDER – SPI Driver for Enhanced Relay Control Smart Multichannel Switches

SPIDER products are the smallest relay drivers in the market with innovative features and packages.

With the SPIDER family Infineon offers a wide choice of integrated multichannel switches specially designed for the control of small loads like relays, LEDs and small motors.

The SPIDER family consists of two subfamilies SPIDER Low-Side (LS) and High-/Low Side (HS/LS).

The SPIDER Low-Side family members are available as four and eight channel versions scalable by current capability and featureset.

The SPIDER High-/Low-Side family members are eight channel devices with four HS, two Configurable and two LS channels. They can be selected by package, current capability and featureset.

The SPIDER families offer not only the scalability through the driving concept and the number of channels but also the flexibility regarding enhanced features like parallel inputs for PWM, limp home and low-voltage cranking.

A variety of packages is available in order to satisfy different application needs.

SPIDER Low-Side (LS)

The new modular low-side driver family scaled by channels (four and eight channels), RDS(ON), packages and add-on features.

This family is especially designed for low-side driving of inductive loads like relays and resistive loads like small LEDs. The Serial Peripheral Interface (SPI) is utilized for control and diagnosis of the device and the loads. It provides daisy-chain capability in order to assemble multiple devices in one SPI chain by using the same number of microcontroller pins.

The devices are equipped with up to four input pins that can be individually routed to the output control of some channels, thus offering complete flexibility in design and PCB layout.

A Limp Home Pin (LHI) offers the capability of driving dedicatedchannels in the event of fail-safe mode.

Key FeaturesFull flexibility for a number of channels, ��

with current capabilities and different feature-setsPin compatibility between TLE 7240SL/43SL/44SL��

Fail safe mode allows functionality also ��

in case of stuck microcontroller

SPIDER High-Side/Low-Side Enhanced

The new SPIDER configurable HS/LS enhanced modular family comes with a standard 8-channel output incorporating two low-side drivers, four high-side drivers and two auto-configuring drivers. These can be used in high-side or low-side configurations just by connecting the load accordingly. Protective and diagnostic functions adjust automatically to the chosen configuration.

The SPIDER HS/LS enhanced family comes with a similar set of protective and diagnostics functions as that provided with the LS family. In addition, the devices protect themselves with build-in reverse polarity protection for the logic part. In the case of loss of module ground, the device changes and stays securely in the OFF state, in order to avoid any erratic behavior.

Key FeaturesFull flexibility due to combined High-Side and Low-Side ��

channels with different feature-sets and current capabilitiesPin compatibility between different feature-set versions��

Software compatibility between all versions��

Feature Description

Always the perfect fit thanks to the outstanding features available in different versionsThe SPIDER HS/LS enhanced family offers a wide range of scalable solutions for applications like body controllers and smart junction boxes.Besides the scalability over current, this family also delivers advanced flexibility thanks to features such as parallel inputs for PWM, Limp Home, and low-voltage cranking.

Current capabilityThree different packages are available to satisfy different requirements in term of load current, power dissipation and board space.

13

Limp HomeThe Limp Home mode operates independently of the digital power supply. An additional pin LHI switches the devices into a predefined state. In this state, the SPI commands are ignored and the input pins are routed to dedicated outputs. All other outputs are switched OFF.

CrankingThe cranking feature enables the devices to keep their state at very low battery voltage. This is enabled by an integrated power supply capable of supporting harsh cranking requirements (with battery level down to 4V) that works independently of the digital power supply.
