HI-8430, HI-8431

8-Channel, Ground /Open, or Supply / Open Sensor

4-channel 200 mA Supply / Open Driver

August 2013

· Airbus ABD0100H compliant

GENERAL DESCRIPTION

· 4 High-Side 200 mA Drivers

The HI-8430 is a combined 8-channel discrete-to-digital

sensor and quad high side driver fabricated with Silicon-

on-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.

· 4.5 Ohm On Resistance VLOGIC Inputs Control 5V to

28V High Side Drivers

· Over-Current Fault Detection Signaled by Logic Output

· Max Power Dissipation Automatically Limited by Fault

Protection

· Diode Clamps for Discharging Inductive Loads

APPLICATIONS

· Avionics Discrete to Digital Sensing

· Relay Driver

All sense inputs are internally lightning protected to

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

components.

· Lamp driver

· Discrete Signaling

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 pin and is fully

fault protected. Over-current conditions, such as a short

circuit, are detected and inhibited while signaling the fault

condition at the corresponding logic output. These four

FAULT outputs are also available in a combined OR output.

The outputs are fully protected from transients when

driving relays.

The HI-8431 is a smaller, reduced pin version of the HI-

8430 and is available in a 32-pin PQFP or 5mm x 5mm

QFN. It has all the features of the HI-8430 except the

individual fault detection outputs, tri-state pin selection and

fixed internal thresholds.

Interface to the digital subsystem is simple CMOS logic

inputs and outputs. The logic pins are compatible with 5V

or 3.3V logic allowing direct connection to a wide range of

microcontrollers or FPGAs.
