TLE 723xSL / SE / EM - SPI Drives for Enhanced Relay Control

Block diagram TLE 7239SL / 36SE / 36EM

The Infineon SPIDER family has nine new enhanced high-side / low-side (HS/LS) members. They are all eight-channel SPI-controlled combined high- and 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 devices offer limp-home or low-voltage cranking (down to 4.0V) functionality. The subfamily devices are pin-compatible.

Logic part of all devices is protected against reverse battery 4 high-side, 2 configurable, 2 low-side channels TLE 723xSL 6 x 230mA; 2 x 130mA PG-SSOP24 TLE 723xSE 6 x 280mA; 2 x 140mA PG-DSO-20 TLE 723xEM 6 x 350mA; 2 x 175mA PG-SSOP24-EP TLE 7237SL / 34SE / 34EM 3 parallel input pins TLE 7238SL / 35SE / 35EM 2 parallel input pins, 2 limp-home channels TLE 7239SL / 36SE / 36EM 2 parallel input pins, 2 limp-home channels, cranking down to 4.0V
