MAX14949EWE+

MAX14949EWE+ is an isolated RS-485/RS-422 transceiver that provides 5000VRMS (60s) of galvanic isolation between the cable side (RS-485/RS-422 driver/receiver-side) and the UART side of the device. This isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. This device allows for robust communication up to 500Kbps. This device includes an integrated 450KHz transformer driver for power transfer to the cable-side of the transceiver using an external transformer. An integrated LDO provides a simple and space-efficient architecture for providing power to the cable-side of the IC. This device includes one half-duplex driver/receiver channel. The receiver is 1/8-unit load, allowing up to 256 transceivers on a common bus. It is used in applications such as industrial automation equipment, programmable logic controllers, HVAC, and power meters.
