Hi Team,

Does we have any solution can replace RT9553A?

I use cross reference search RT9553A, it show INA300 result, but it seems INA300 only support OC.

Does we have any other solution can support Current/Voltage Sensing and Protection IC like RT9553A?

Thanks team!

    Hello Kai,

    Thanks for reaching out on the forum.  We only have one analog output device that monitors the bus voltage and that is the INA223.  However, it does not have an alert function.  We do have other devices with built in comparators and these can be used for over current detection.  Some alternatives to the INA300 include the INA301, INA302, INA303, and the INA381.  If your customer is open to a digital output device, we have several power monitors that have bus voltage sensing and alert capabilities.  There are quite a few that can be found here.  Aside from the voltage sensing, is there any other particular specification or feature that is very important to your customer?
