GENERAL DESCRIPTION
The HI-8425 is a combined 8-channel discrete-to-digital sensor and quad low side driver fabricated with Silicon-on Insulator (SOI) technology for robust latch-up free operation. Sense detection can either be GND/Open or Supply/Open as configured by the SNSE_SEL pin. Supply/Open sensing is also referred to as 28V/Open sensing. The sensing circuit window comparator thresholds can be fixed at the internal programmed values or can be set externally at the HI_SET and LO_SET pins, as selected by the THS_SEL pin. The digital SENSE outputs can be tristated by taking the OE pin high.
