Product Overview
MAX14948EWE+T 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. Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. It includes one half-duplex drive/receive channel. The receiver is 1/8-unit load, allowing up to 256 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. It is approved by UL according to UL1577, cUL according to CSA bulletin 5A. It is used in applications such as industrial automation equipment, programmable logic controllers, HVAC, and power meters.
- Integrated LDO for cable-side power, compliant with RS-485/EIA-485 standard
- ±30kV ESD (HBM) on driver outputs/receiver inputs, thermal shutdown
- 5KVRMS withstand isolation voltage for 60s (VISO)
- 1200VPEAK maximum repetitive peak-isolation voltage (VIORM)
- 848VRMS maximum working-isolation voltage (VIOWM)
- VDDA supply voltage range from 1.71V to 5.5V
- Supply current is 4mA typical at (VDDA – VGNDA = 1.71V to 5.5V)
- Load regulation is 0.19mV/mA typical at (VLDO = 5.68V, ILOAD = 20mA to 40mA)
- Operating temperature range from -40°C to +85°C
- 16-pin WSOIC package
