Evaluates: MAX14915 MAX14915 Evaluation Kit General Description Features The MAX14915 evaluation kit (EV kit) provides a proven Robust Operation with Wide Range Of Input Voltages design to evaluate the MAX14915, octal high-side switch and Load Conditions with extended diagnostics. The EV kit includes the VDDOK Indication MAX14915 evaluation board and a graphical user interface LED Indication of Channels Status and Fault (GUI) that provides communication from a PC to the Conditions target device through a USB port and the USB2GPIO Fast Inductive Load Demagnetization interface board. The USB2GPIO EV kit should be ordered Open-wire, Overload, Undervoltage, Overcurrent, separately. Thermal Shutdown Fault Conditions Indication Supports Watchdog and SYNCH Features The GUI is compatible with Windows 10 for exercising Communication Error Indication the features of the MAX14915 IC. The EV kit GUI allows Wide Logic Voltage Range individually controlling of eight high-side switches through Pin Addressable SPI Communication the high-speed SPI interface and receive a diagnostic -40C to +125C Temperature Range information from the MAX14915, including open-wire/ Proven PCB Layout open-load conditions, state of the output channels, Fully Assembled and Tested multiple undervoltage alarms, global and per channel Windows 10 Compatible Software overtemperature alarms, and multiple fault alarms. The MAX14915 EV kit must be powered from an external +24V power supply and can consume more than 10A when fully loaded. The USB2GPIO interface board is Ordering Information appears at end of data sheet. powered from the USB port. The MAX14915 EV kit board comes with a MAX14915AFM+ installed in a 48-pin, 6 x 6mm FC2QFN package.
