NSiP83086
NSiP83086 is Signal Isolated RS-485 Transceiver manufactured by NOVOSENSE.
NSi P83086 Signal Isolated RS-485 Transceiver With Integrated DC to DC Converter
Datasheet (EN) 1.0
Product Overview
NSi P83086 series are high reliability isolated full duplex RS-485 transceiver with integrated DC to DC converter. The NSi P83086 isolated DC to DC converter uses on-chip transformer. The feedback PWM signal is sent to primary side(Isolator Side1) by a digital isolator based on Novosense capacity isolation technology. The NSi P83086 series are safety certified by UL1577 supporting 5k Vrms insulation withstand voltage, while the high integrated solution can help to simplify system design and improve reliability. The Bus pins of NSi P83086 are protected from ±8k V system level ESD to GND2. The device Features a fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. The device have 96k Ω input impedance that allows up to 256 transceivers on the bus.
