Product Overview
MAX22028AWA+ is a compact isolated RS-485/RS-422 transceiver that provides 3.5KVRMS of digital 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 features proprietary auto direction control making this device ideal for applications such as isolated RS-485 ports, where the driver input is used in conjunction with the driver-enable signal to drive the differential bus. The driver outputs and receiver inputs are protected from ±10kV electrostatic discharge (ESD) to GNDB on the cable side, as specified by the human body model (HBM). It is used in applications such as utility meters, industrial automation equipment, programmable logic controllers, and HVAC.
- UL according to UL1577, cUL according to CSA bulletin 5A (safety approval)
- Fully isolated half-duplex RS-485/RS-422 transceivers
