MAX14850PMB1

MAX14850PMB1 Peripheral Module

Description

The MAX14850PMB1 peripheral module utilizes the MAX14850 digital isolator to isolate another SPI- or UARTbased module from any host system that utilizes PmodKcompatible expansion ports configurable for either a UART or SPI interface. This peripheral module is first plugged into the host Pmod port. Another UART- or SPI-based module plugged into the 12-pin Pmod-compatible connector on this peripheral module is galvanically isolated from the host and referenced to a secondary power supply connected to this peripheral module.
The IC is a 6-channel digital isolator utilizing Maxim’s proprietary process technology, whose monolithic design provides a compact and low-cost transfer of digital signals between circuits with different power domains. Of the six total channels, the four unidirectional channels are each capable of DC to 50Mbps, with two of the four channels passing data across the isolation barrier in each direction. The two bidirectional channels are open drain and each is capable of data rates from DC to 2Mbps.

Refer to the MAX14850 IC data sheet for detailed information regarding operation of the IC.
