Part Number: INA233
Other Parts Discussed in Thread: INA169

Hi team,

My customer used our ina233 & ina169 for their current sensing design as below figure.

May I have your help to review it? Thanks.

    Hi,

    For the INA233 schematic, you may want to move CC19 to the other side of RC11/RC15. For the INA169 circuit, you may want to select the correct gain resistors R842/844.

    Depending on what GPIO1 is connected to and its function, it may be necessary to consider whether a comparator with hysteresis is needed.

    Everything else is in line with typical configurations.

    Regards, Guang
