The MAX14917 has eight high-side switches specified to deliver up to 700mA (min) continuous current per channel. The high-side switches have on-resistance of 120mΩ (typ) at 25°C ambient temperature.

The device has an SPI interface that can be daisy chained, allowing communication with multiple MAX14917 devices utilizing a common SPI chip select (active-low CS). There are also per-channel overload diagnostics provided through the SPI interface. Two watchdog timers provide an additional safety check of the master-to-device connectivity.

The MAX14917 features a 4 x 4 LED cross-bar matrix, which provides a visual indication of channel status and overload conditions for each channel, and an integrated line-to-ground and line-to-line surge protection provides robustness to the electrical stress as per IEC 61000-4-5 and requires only one TVS on V_DD. The MAX14917 is available in a compact 48-pin 6mm x 6mm FC2QFN package.

Product Details

The MAX14917 evaluation kit (EV kit) provides a proven design to evaluate the MAX14917 octal high-side switch. The EV kit includes the MAX14917 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 MAX14917 IC. The EV kit GUI allows individual control of eight high-side switches through the high-speed SPI interface and receives diagnostic information from the MAX14917 per channel overload diagnostics, communication errors, and thermal shutdown diagnostics.

The MAX14917 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 powered from the USB port.

The MAX14917 EV kit board comes with a MAX14917AFM+ installed in a 48-pin, 6mm x 6mm FC2QFN package.
