Octal Discrete-to-Digital Sensing IC with Quad High-Side Drivers and Built-In Lightning Protection

Friday, October 05, 2012

Mission Viejo, CA (October 5, 2012)Holt Integrated Circuits today announced the introduction of HI-8430, a new 3.3V octal discrete-to-digital sensing IC with quad high-side drivers and built-in lightning protection. The device is also fully compliant to Airbus ABD0100H.

The eight sensing channels may be configured to detect either GND/Open or 28V/Open, with programmable thresholds and hysteresis. The device operates from a 3.0V to 5.5V supply with sense detection levels from 2V to 21V. In addition, four high-side output drivers are capable of driving 200mA loads. Each individual driver has over-current shutdown protection, with fault detection signaled on external pins.

This type of device may be used in a multitude of aircraft sensing applications, such as “hatch open” and “wheels up” indicators. The built-in driver outputs are ideal for driving relays or display panel warning lights. 

 This product provides customers with a flexible, easy-to-use solution for analog voltage sensing and high-side driver applications,” said Anthony Murray, Director of Business Development at Holt. “The broad functionality and on-chip lightning protection result in an unprecedented component-count reduction, giving customers the most robust, cost effective solution on the market today.”

The HI-8431 is a more compact version of the HI-8430, with the same functionality minus individual fault detection pins. Fault detection is still functionally realized in the HI-8431 using a single-pin combined ORed output.

The devices are available in industrial −40oC to +85oC and extended −55oC to +125oC temperature ranges and come in multiple standard package options, including 44‑pin PQFQ and compact 40-pin or 32-pin QFNs.
