The MAX14916 has eight high-side switches specified to deliver up to 1.1 A (min) continuous current per channel. The two adjacent channels can be paralleled to form four 2.4 A high-side switches. The high-side switches have on-resistance of 250 mΩ (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).

Evaluation Kit for the MAX14916

The MAX14916 evaluation kit (EV kit) provides a proven design to evaluate the MAX14916, 2.4 A (min) quad high side switch with extended diagnostics. The EV kit includes the MAX14916 evaluation board and a graphical user interface (GUI) that provides communication from a PC to the target device through a USB port and the USB2GPIO interface board. The USB2GPIO EV kit should be ordered separately.

The GUI is compatible with Windows 10 for exercising the features of the MAX14916 IC. The EV kit GUI allows individually controlling of eight high-side switches, which hardware configured for quad high-current operation, through the high-speed SPI interface and receive a diagnostic information from the MAX14916, including open-wire/ open-load conditions, state of the output channels, multiple undervoltage alarms, global and per-channel overtemperature alarms, and multiple fault alarms.

The MAX14916 EV kit must be powered from an external +24 V power supply and can consume more than 10 A when fully loaded. The USB2GPIO interface board is powered from the USB port.

The MAX14916 EV kit board comes with a MAX14916AFM+ installed in a 48-pin, 6 x 6 mm FC2QFN package.
