SPIDER+ | Multichannel SPI Driver Enhanced Relay Control

Überblick

SPIDER+ devices are equipped with limp home and cranking, very low current consumption, enhanced diagnosis features, excellent thermal performance (exposed pad packages) and an input mapping function for the 2 direct inputs

Furthermore the the new 8 ch HS device offers a very cost efficient solution to drive small HS loads, including open load at ON detection. The family approach with consistent SPI registers, identical output stages for all channels and a comprehensive pin-to-pin compatibility reduce the design effort and therefore system costs down options as well as partitioning adjustments without a PCB re-design. Small TSDSO-14 and 24 pin packages realize PCB space savings.
