INA155/INA156 is used to form a single-supply high-side current monitor for detecting load current
Source: InternetPublisher:同住地球村 Keywords: Current Monitor Updated: 2024/09/11
As shown in the figure, a single-power supply high-end current monitor composed of INA155/INA156 is used to detect the load current. A sampling resistor (0.02Ω) is connected in series between the power supply and the load. When the load current flows through the sampling resistor, a voltage drop is generated. The voltage drop reflects the change of the load current. This sampling voltage is input to INA155/156 for amplification and output. The gain of this circuit is 10, and the 1st and 8th pins are not connected.
