MAX14850PMB1#

MAX14850PMB1# is a peripheral module that utilizes the MAX14850 digital isolator to isolate another SPI or UART based module from any host system that utilizes Pmod™ compatible 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 12-pin Pmod-compatible connector on this peripheral module is galvanically isolated from host and referenced to a secondary power supply connected to this peripheral module. The IC is a 6-ch 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 6 total ch, the 4 unidirectional ch are each capable of DC to 50Mbps, with 2 of the 4 channels passing data across the isolation barrier in each direction. Two bidirectional channels are open drain and each is capable of data rates from DC to 2Mbps.

• Isolates SPI- or UART-based Pmod-compatible modules from the host system
• Data rates from 2Mbps to 20Mbps or greater, depending on configuration
• 2-pin header to connect external voltage for isolated module
• 600VRMS isolation for 60s
• Isolates four SPI or UART signals and two control signals
• Short-circuit protection on unidirectional outputs
• 12-pin Pmod-compatible male connector to host
• 12-Pin Pmod-compatible female connection for module to be isolated
• Proven PCB layout
• Fully assembled and tested
