HI-8436

32-Channel Ground/Open or Supply/Open

Low Threshold Sensor with SPI Interface

August 2013

APPLICATION

· Avionics Discrete to Digital Sensing

GENERAL DESCRIPTION

The HI-8436 is a 32-channel discrete-to-digital sensor

fabricated with Silicon-on-Insulator (SOI) technology

designed to interface with a Serial Peripheral Interface

(SPI).

PIN CONFIGURATIONS

Four banks of 8 sense inputs can be programmed as either

GND/Open or Supply/Open sensors. Supply/Open

sensing is also referred to as 28V/Open sensing.

All sense inputs are internally lightning protected to

DO160G, Section 22, Cat AZ, BZ and ZZ without external

components.

The sensing circuit window comparator thresholds are set

by programming the center threshold and hysteresis

registers to values from 0.4V to 5.2V. The digital values of

the sensed inputs can be read either one bank at a time or

all 4 banks with one command.

Each bank of sensors have a VWETn pin available for

optional application of a voltage higher than the logic

supply to provide wetting current to Ground side relay

contacts. If the Ground offset is small, then the wetting

source will automatically be provided from VLOGIC without

connecting VWETn.

44 Pin Plastic Quad Flat Pack (PQFP)

10mm x 10mm

Interface to the digital subsystem is simple CMOS logic

inputs and outputs. The logic pins are compatible with 3.3V

logic allowing direct connection to a wide range of

microcontrollers or FPGAs.
