HI-8435PQIF

Power Management - Specialized Overview

The HI-8435PQIF is a 32-channel discrete-to-digital sensor interface fabricated with Silicon-on-Insulator (SPI) technology. It operates on a single supply voltage ranging from 3V to 3.6V, with typical operation at 3.3V or 3.6V. The device features a Serial Peripheral Interface (SPI) for data communication and includes built-in lightning protection. It is housed in a 44-pin Plastic Quad Flat Pack (PQFP) package and supports an operating temperature range of -40°C to +85°C.
