MAX14853GWE+

MAX14853GWE+ is an isolated RS-485/RS-422 transceiver that provides 2750VRMS (60s) of galvanic isolation between the cable side (RS-485/RS-422 driver/receiver side) and the UART side of the device. Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. It 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. It includes one drive channel and one receive channel. The receiver is ¼-unit load, allowing up to 128 transceivers on a common bus. The driver outputs and receiver inputs are protected from ±35kV electrostatic discharge to GNDB on the cable-side, as specified by the Human Body Model (HBM). Applications include industrial automation equipment, programmable logic controllers, HV AC, power meters.
