32-Channel Ground/Open or Supply/Open
Low Threshold Sensor with SPI Interface
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).
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
application of a voltage to supply pull up current to the
GND/Open sensor.
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.
