HI-8425, HI-8426
8-Channel, Ground /Open, or Supply / Open Sensor 4-channel 200 mA Ground / Open Driver
GENERAL DESCRIPTION
The HI-8425 is a combined 8-channel discrete-to-digital sensor and quad low side driver fabricated with Silicon-onInsulator (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.
