SPIDER HS/LS Enhanced

SPI Driver for Enhanced Relay Control TLE 723xSL/3xSE/3xEM

The Infineon SPIDER high-side / low-side HS/LS enhanced family consists of nine family members. They are all eight-channel SPI-controlled combined highand low-side switches especially designed to drive automotive relays.

The HS/LS family consists of three sub-families -SL, -SE and -EM , offering different combinations of current capability and package size. Within these sub-families, the device can be selected by its featureset limp-home or lowvoltage cranking down to 4.0V .

The subfamily devices are pin-compatible and devices with same featureset are software compatible. So it is easily possible to switch from one device to another.

All devices are protected against short circuit and overload and especially designed to fulfil the requirements of the harsh automotive environment.
-- High-side and low-side driven automotive relays -- Small LEDs and other small signal loads

Key Features
-- High flexibility due to 4 high-side 2 configurable, 2 low-side channels
-- SPI communication -- Short circuit and over load
protection, thermal shutdown -- Scalable by featureset and current
capability -- Cranking and limp home version
available

Key Benefits
-- Reduced microcontroller I/Os -- Small package to reduce board
space -- Possibility to address safety critical
application under harsh automotive conditions -- If you know one device you know the whole family
