Other Parts Discussed in Thread: INA290, INA193
Hello,
My customer designed INA290 for DC/DC output voltage monitoring as shown below.
P15V_CS is output normally, but N15V_CS is not output normally.
N15V_CS should output 0.016ohm * 0.4A * 50V/V = 0.32V, but 0V is output. Even if the load on the N15V_CS output terminal is changed from 0.4A to 0.8A, the N15V_CS voltage is measured as 0V.
There was no problem when they used the INA193 with the same DC/DC as shown below.
Please advise on the cause and solution for the issue with negative voltage monitoring.
Thank you.
JH
