INA290: loading question

Part Number: INA290


Tool/software:

Hello,

We’d like to use this device to monitor the input current to a PCBA on a 48V line.

 

The INA290 will be powered off a 3.3V supply that comes up a few hundred milliseconds after the input supply voltage is present (3.3V powered by 48V rail).

 

Will the INA290 in any way load the 48V input power supply rail before his 3.3V supply rail is in regulation?

Thanks,

Adam
