MAX14916/MAX14916A Switches

ADI's MAX14916 and MAX14916A are equipped with eight high-side switches with on-resistance of only 120 mΩ (typ) or 250 mΩ (max) at +125°C ambient temperature. Each channel is specified to handle up to 1.1 A (MAX14916) or 1.5 A (MAX14916A) of continuous current. Similarly, two adjacent channels can be driven together to form four 2.4 A (MAX14916) or 3 A (MAX14916A) switches.

The serial peripheral interface (SPI) 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 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 indicate 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 V_DD. Integrated surge protection works for quad and octal configurations. The MAX14916 and MAX14916A are available in a compact 48-pin 6 mm x 6 mm QFN package.
