The MAX14915 has eight high-side switches specified to deliver up to 700mA continuous current. The high-side switches have on-resistance of 250mΩ (max) at 125°C ambient temperature.

The SPI interface has a built-in chip addressing decoder, allowing communication with multiple MAX14915s utilizing a common SPI chip select (active-low CS).

The SPI interface provides flexibility for global and per-channel configuration and diagnostic, including over and undervoltage detection, open wire/load detection, overload and current limiting reporting, thermal conditions reporting, and more.

Open load detection detects both open-wire/open-load conditions with switches in the on and off states. LED drivers provide indication of 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 TVS on VDD.

The MAX14915 is available in a compact 48-pin 6mm x 6mm QFN package.

Product Detail

The MAX14915 evaluation kit (EV kit) provides a proven design to evaluate the MAX14915, octal high-side switch with extended diagnostics. The EV kit includes the MAX14915 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 MAX14915 IC. The EV kit GUI allows individually controlling of eight high-side switches through the high-speed SPI interface and receive a diagnostic information from the MAX14915, 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 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 powered from the USB port.

The MAX14915 EV kit board comes with a MAX14915AFM+ installed in a 48-pin, 6 x 6mm FC2QFN package.
