Quad High Side and Octal Low Side Switch for Automotive

NOTES:
1 SPI I/O and internal logic operational. Outputs will recover in instructed state when VPWR voltage level returns to normal as long as the level does not go below
UVPOR.
2 VPWR Voltage levels less than UVPOR will result in a reinitialization of all internal logic when the level returns to normal levels.
3 Output OFF Open Load Detect Current is the current required to flow through the load for the purpose of detecting the existence of an open load condition when the
specific output is commanded OFF.
4 Output fault detect threshold with outputs programmed OFF.
5 Output fault detect threshold with outputs programmed OFF. For the LS Outputs, fault detect thresholds are the same for output open and battery shorts.
6 Guaranteed by Design; not production tested.
