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 t...
