产品详情
The MAX14916 has eight high-side switches specified to deliver up to 1.1A (min) continuous current per channel. The two adjacent channels can be paralleled to form four 2.4A high-side switches. The high-side switches have on-resistance of 250mΩ (max) at 125°C ambient temperature.
The SPI interface has a built-in chip addressing decoder, allowing communication with multiple MAX14916s utilizing a common SPI chip select (active-low CS pin pulled low). The SPI interface provides flexibility for global and per-channel configuration and diagnostic, including 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. Integrated line-to-ground and line-to-line surge protection only requires a TVS on VDD. Integrated surge protection works for quad and octal configuration. The MAX14916 is available in a compact 48-pin 6mm x 6mm QFN package.Applications
