Thank you for this video. I could use your help. I want to charge batteries with my Siglent PSU. I need the charge cycle to stop, when the current drops to 200mA. I can do this in the PSU's software, but I am not much of a coder. So, I am needing an adjustable low current shut off circuit. Thank you for your consideration of it. Using an Attiny85 and a sense resistor might work?
Thank you, Im learning how to use batteries in project, and those Li-ion scares the shit out of me since the BMS I bought from amazon seems to do nothing
Some microcontroller boards have a pushbutton from the reset pin to ground to manually put the system into reset. The DS1233A has a feature that detects this button press and debounces it for 350 ms to stop multiple resets which can cause the firmware to become errratic. This feature will not be activated when used as a low battery alarm.
I have been working with a local interest group here involved in product development and manufacturing. Didn't think I would be missed as there are many big named You Tube channels out there with similar content. It has turned out to be a time consuming project.

Check Adafruit website for a current sensor module to detect your 200 mA current trigger for shutdown.
microcontroller is wasted in this project
Useful tip, thanks!
Your're welcome. Glad it was helpful.

Wow, what a useful IC. And easy to implement.
Yes, it's been around for a long time.
Another great circuit to bookmark... Thanks. Needed something simple like that a few years ago.
You're welcome! A nice little hack to keep in the back of your mind.
Can you explain the button debounce on the data sheet?

Great tip of the day. Thanks
Welcome!
I vaguely remember a chip named MAX809 that worked in a similar way, I will have to investigate. Thank you for another helpful tip.
Yes, the MAX803 is basically the same chip bit only available in SMD, so not breadboard friendly.
What a awesome little project! Just in time, I'm working on my DIY lawnmower and this will detect low battery power! Thnxs for sharing!
Glad I could help!
Very good, Ken.
Thanks John.
Where you been?, enjoying summer?

@@0033mer similar but not the same, your content and style is unique.
Thanks for the feedback. Appreciate that!
