HI-8425 Datasheet | HOLTIC

DESCRIPTION The HI-8425 is a bined 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 parator 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. All sense inputs are internally lightning protected to DO160G, Section 22, Cat AZ, BZ and ZZ without external ponents. The HI-8425 also offers four low side switches each capable of sinking 200 m A of current. Each switch transistor is controlled by its own digital input pin...
