Product Brief SPIDER HS/LS Enhanced SPI Driver for Enhanced Relay Control TLE 723xSL/3xSE/3xEM Key Features „„ Logic part of all devices is protected against reverse battery „„ High flexibility due to 4 high-side 2 configurable, 2 low-side channels 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. „„ SPI communication „„ Short circuit and over load „„ Scalable by featureset and current protection, thermal shutdown 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 Applications „„ High-side and low-side driven automotive relays „„ Small LEDs and other small signal loads www.infineon.com/spider Product Brief SPIDER HS/LS Enhanced TLE 723xSL/3xSE/3xEM Block Diagram TLE 7239SL VBB LHI Power Supply Temperature Sensor Limp Home Mode Activation High-Side Gate Control Input Mux Short Circuit Detection IN1 IN2 Input Register VDD CS SCLK SI SO Control, Diagnostic and Protective Functions Open Load Detection D4 D5 Auto Configuring Gate Control Stand-by Control SPI OUT0 OUT1 OUT2 OUT3 S5 S4 OUT6 OUT7 Diagnosis Register Low-side Gate Control Reverse Polarity Protection GND SUB SPIDER HS/LS Enhanced Family Product Nominal Current Package Features TLE 7237SL 6*230mA, 2*130mA PG-SSOP-24 3 Direct Inputs TLE 7238SL 6*230mA, 2*130mA PG-SSOP-24 2 Limp Home Channels TLE 7239SL 6*230mA, 2*130mA PG-SSOP-24 2 Limp Home Channels & Cranking TLE 7234SE 6*280mA, 2*140mA PG-DSO-20 3 Direct Inputs TLE 7235SE 6*280mA, 2*140mA PG-DSO-20 2 Limp Home Channels TLE 7236SE 6*280mA, 2*140mA PG-DSO-20 2 Limp Home Channels & Cranking TLE 7234EM 6*350mA, 2*175mA PG-SSOP-24 Exposed Pad 3 Direct Inputs TLE 7235EM 6*350mA, 2*175mA PG-SSOP-24 Exposed Pad 2 Limp Home Channels TLE 7236EM 6*350mA, 2*175mA PG-SSOP-24 Exposed Pad 2 Limp Home Channels & Cranking Published by Infineon Technologies AG 85579 Neubiberg, Germany © 2010 Infineon Technologies AG.
