Part Number: INA226

Can INA226 use the condition of voltage monitor (VBUS pin) only?

If possible, are unused current sense pin(ViN+ and VIN- pin) connect to GND correct?

Or, are these pin Floating OK?

Best regards,

Hi Satoshi,

Yes INA226 can be used to measure VBUS only. The current sense pins can be left floating, however I would connect them to a fix voltage potential, and ground is probably the best choice.
