-48V Telecom Current/Voltage/Power Sense with Isolation
Description
This verified design can accurately measure current: voltage and power on a bus that carries -48V and is able to provide this data using an I²C compatible interface. This design is targeted for Telecom applications because the most common Telecom equipment’s are fed with this negative supply voltage. It uses INA226 and ISO1541. The INA226 is a current shunt and power monitor with an I²C compatible interface. This device will precisely take these measurements and will use ISO1541 to translate the negative voltage to ground referenced signals. The ISO1541 is a low-power: bidirectional I²C compatible isolator.
Features
- Ability to report current: voltage and power on a bus that carries -48VHigh Accuracy:- 10µV Offset (Max)- 0.1% Gain Error (Max) I²C compatible interfaceIsolation friendly for board to board communicationI²C compatible isolation translates -48V reference to ground referenced signals
