GENERAL DESCRIPTION
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.
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 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.
