HI-8430

November 2015 HI-8430, HI-8431 8-Channel, Ground /Open, or Supply / Open Sensor 4-channel 200 mA Supply / Open Driver GENERAL DESCRIPTION The HI-8430 is a combined 8-channel discrete-to-digital sensor and quad high side driver fabricated with Siliconon-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 tri-stated by taking the OE pin high. All sense inputs are internally lightning protected to DO160G, Section 22, Cat AZ, BZ and ZZ without external components. The HI-8430 also offers four high side switches each capable of sourcing 200 mA of current. Each switch transistor is controlled by its own digital input p...
