HI-8425, HI-8426

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

4-channel 200 mA Ground / Open Driver

August 2013

GENERAL DESCRIPTION

· Airbus ABD0100H compliant

The HI-8425 is a combined 8-channel discrete-to-digital

sensor and quad low 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 Low-Side 200 mA drivers

· 4.5 Ohm On Resistance

· 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

All sense inputs are internally lightning protected to

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

components.

· Relay Driver

· Lamp driver

· Discrete Signaling

The HI-8425 also offers four low side switches each

capable of sinking 200 mAof 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-8426 puts all of the features of the HI-8425 except

the individual Fault Detection Outputs, Tri-state pin

selection and fixed internal thresholds into a 32-pin Chip

Scale Package (QFN) which measures only 5mm x 5mm.

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.
