Product Details

This evaluation kit provides a proven design to evaluate the MAX14916 and MAX14916A, eight-channel 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# board should be ordered separately. The MAX14916 EV kit comes with a MAX14916AFM+ in a 48-pin, 6mm x 6mm FC2QFN package, installed as U1. The EV kit can also be used to evaluate the MAX14916AAFM+. The user needs to order the MAX14916AAFM+ samples and replace U1.

The GUI is compatible with Windows^®10 for exercising the features of the MAX14916 IC. The EV kit connects the two adjacent channels of the MAX14916 together for quad high-output current operation. The EV kit software, however, gives access to the full register map, allowing individual control of the eight high-side switches. Refer to the MAX14915 EV kit to evaluate the octal output configuration. The software also retrieves all the diagnostic information from the MAX14916, including open-wire conditions, state of the output channels, multiple undervoltage alarms, global and per-channel overtemperature alarms, and other fault alarms.

The MAX14916 EV kit must be powered from an external +24V power supply and can consume more than 16A when fully loaded. The USB2GPIO# interface board is powered from the USB port.

A single TVS diode on VDD protects all output channels against ±1kV/42Ω IEC 61000-4-5 surge transients.

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