Description
BL1590 is a 3~5.5V wide power supply, half-duplex RS-485 transceiver, the chip contains a driver and a receiver. Can achieve up to 16Mbps error-free data transmission. The BL1590 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 shorted.
BL1590 has excellent driving capability, and the driver can provide a differential output voltage of 3.4V under the condition of 5V power supply and 54Ω load. BL1590 supports hot-swapping function, the driver and receiver are in the off state during power-on, to avoid conflicts on the bus when plugging and unplugging.
The BL1590 has a 1 -unit load receiver input impedance, allowing up to 32 transceivers on the bus . The I/O pin ESD protection capability reaches 15KV IEC 61000-4-2 , contact discharge.
