HI-8430, HI-8431
8-Channel, Ground /Open, or Supply / Open Sensor
4-channel 200 mA Supply / Open Driver
GENERAL DESCRIPTION
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.
All sense inputs are internally lightning protected to
DO160G, Section 22, Cat AZ, BZ and ZZ without external
components.
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.
