Trade Name:MAX14917AFM
Data Manual:MAX14917AFM.pdf
Brand:Maxim
Particular Year:23+
Package:FCQFN-48
Delivery Date:New and Original
Stock: 1000pcs
The MAX14917AFM has eight high-side switches that provide up to 700mA (minimum) continuous current per channel. The high-side switches have an on-resistance of 120mΩ (typical) at 25°C ambient temperature.
The device has a daisy-chainable SPI interface that supports communication with multiple MAX14917 devices using a general-purpose SPI chip select (active low CS) signal. Overload diagnostics are also provided for each channel via the SPI interface. Two watchdog timers provide an additional safety check on the host-to-slave connection.
The MAX14917AFM features a 4 x 4 LED aspect matrix that provides visual indication of channel status and overload conditions for each channel, while integrated line-to-ground and line-to-line surge protection provides tolerance to electrical stress according to IEC 61000-4-5 and requires only one TVS at VDD.The MAX14917AFM is available in a compact 48-pin 6mm x 6mm FC2QFN package.
