MAX14915AFM+

MAX14915 is a compact industrial octal high-side switch with diagnostics. It has eight high-side switches specified to deliver up to 700mA continuous current. The high-side switches have on-resistance of 250mohm (max) at 125°C ambient temperature. The SPI interface has a built-in chip addressing decoder, allowing communication with multiple utilizing a common SPI chip select (active-low CS). The SPI interface provides flexibility for global and per-channel configuration and diagnostic, including over and undervoltage detection, open wire/load detection, overload and current limiting reporting, thermal conditions reporting, and more. Open load detection detects both open-wire/open-load conditions with switches in the 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. Application includes industrial digital outputs, PLC systems.
