Description
BL3085N is a 5V power supply, half-duplex, adaptive bus polarity RS-485 transceiver, the chip contains a driver and a receiver. BL3085N integrates the bus polarity correction circuit, and the polarity discrimination time is 80ms . In the communication system composed of RS-485 communication chip , it can automatically adapt to the polarity of the bus port.
The BL3085N uses a slew-rate-limited driver, which can significantly reduce EMI and reflections caused by improperly terminated cables, enabling error-free data transmission up to 500kbps . BL3085N has a built-in fail-safe circuit to ensure that the output of the receiver is in a logic high state when the input of the receiver is open or short-circuited.
BL3085N receiver is 1/8 unit load, allowing up to 256 transceivers to be connected to the bus to realize half-duplex communication. BL3085N I/O pins have 15kV IEC 61000-4-2 contact discharge protection capability.
