The MAX14916 and MAX14916A are equipped with eight high-side switches with an on-resistance of only 120mΩ (typ), or 250mΩ (max) at 125°C ambient temperature. Each channel is specified to handle up to 1.1A (MAX14916) or 1.5A (MAX14916A) of continuous current. Similarly, two adjacent channels can be driven together to form four 2.4A (MAX14916) or 3A (MAX14916A) switches.The SPI interface has a built-in chip addressing decoder, allowing communication with up to four MAX14916 or MAX14916A devices utilizing a common SPI chip select (CS).The SPI interface provides flexibility for global and per-channel configuration and diagnostic, including undervoltage detection, open-wire detection, overload and current limiting reporting, thermal conditions reporting, and more.Each channel is equipped with open-wire detection that can detect an open-load in both switch on and off states. LED drivers provide indication of per-channel fault, status, and supply undervoltage conditions. Internal active clamps allow for fast turn-off of inductive loads.Integrated line-to-ground and line-to-line surge protection only requires a single TVS on VDD. Integrated surge protection works for quad and octal configuration.The MAX14916 and MAX14916A are available in a compact 48-pin 6mm x 6mm QFN package.ApplicationsIndustrial Digital OutputsPLC Systems
