Part Number: ISO3082
We must implement an isolated RS485 Half Duplex Interface with 2500V Isolation and a Slew-Rate limited Driver for 11500 Baud. So we found the IS3092 IC which combines a RS485 Transceiver and a galvanic isolation. The isolated Power for the Transsceiver is generated with an SN6501.
During calculation of power consumption (No Load) we run in a problem:
1. Datasheet page 11, Figure 5. ISO3082 Supply Current vs Data Rate With No Load
The Power Consumption at ICC2 of 25 mA@5V at 100 kBit is significant higher than an discrete Solution ISO7141+SN65HVD3082E (9+5=11 mA)
The faster part, for example ISO0386 (20 Mbaud) consumes only 11 mA at 1 MBaud.
In reply to Dan Kisling:
There are plans to update the ISO3082 family or provide a new series of integrated RS485-Transceiver and Isolator?
