Maximum Continuous Current on SEN-13679 Breakout Board

Components & Accessories Power

Hi SparkFun community. I am hoping someone can help me with what should be a simple question.

Background: I am looking to use the SEN-13679 to create an automatic charger cut off for a li-ion battery pack charger using an Arduino Pro Mini. I already have a CC, CV power adapter that will keep those two values in check on the high end while charging, but I need something that will automatically cut off the charger when the termination current has reached for the battery pack (400mA @ 29.4v). Looking at the datasheet for the ACS723, the maximum continuous current is 65A. However, I know that depending on the traces, they may not be able to handle the maximum power the charger will draw (235W: 8A @ 29.4v).

Question: What is the maximum current (and power) that can be sensed due to the physical limitations of the breakout board? I don’t want to fry the board/IC. :smiley:

Thanks in advance to anyone who reads this!

We haven’t tested the board for maximum current but it should be able to handle at least 10 amps with no problems. :slight_smile:

Thanks for the quick reply Chris! I’ll give it a shot and see how it goes!
