Overview
November 2015 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.
All sense inputs are internally lightning protected to DO160G, Section 22, Cat AZ, BZ and ZZ without external components.
The HI-8425 also offers four low side switches each capable of sinking 200 mA of current.
Each switch transistor is controlled by its own digital input pin a...
