具有集成式分流电阻器和 I2C 接口的隔离式电流检测参考设计
TIDA-01608
概述
This verified design can accurately measure current on a bus that carries hundreds of volts. This design is targeted for solar and server applications due to their wide high-voltage input range requirements. This design uses the INA260 current shunt monitor with integrated shunt resistor for current measurements, two P82B96 bidirectional buffers to facilitate I2C communication, and the ISOW7842 to allow isolated current measurements. The INA260 is limited by a common-mode voltage of 36 V; using the ISOW7842 allows the designer to float the INA260 side of the design to facilitate higher bus voltages.
