Product Details
The MAXM22510 and MAXM22511 isolated RS-485/RS-422, full-duplex, transceiver modules provide 2500VRMS (60s) of galvanic isolation between the cableside (RS-485/RS-422 driver/receiver side) and the UART-side of the device. An integrated DC-DC powers the cable-side of the module. No external components are required.
Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. These devices allow for robust communication up to 500kbps (MAXM22510) and 25Mbps (MAXM22511).
The MAXM22510/MAXM22511 operate from a single 3.3V supply on the UART-side. An integrated DC-DC converter generates the 3.3V operating voltage for the cable-side of the module.
The devices include one drive channel and one receive channel. The receiver is 1/4-unit load, allowing up to 128 transceivers on a common bus.
Integrated true fail-safe circuitry ensures a logic-high on the receiver output when inputs are shorted or open. Undervoltage lockout disables the driver when cable-side or UART-side power supplies are below functional levels.
The driver outputs and receiver inputs are protected from ±35kV electrostatic discharge (ESD) to GNDB on the cable-side, as specified by the Human Body Model (HBM).
The MAXM22510/MAXM22511 are available in an LGA 44-pin package and operate over the -40°C to +105°C temperature range.
