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 VDD. The MAX14917 is available in a compact 48-pin 6mm x 6mm FC2QFN package.
