Hi,
I'd appreciate any suggestions for cheap, available and preferably easy to use
ICs which are designed to be used in a
latching On/Off Power Button circuit.
I am aware that Dave made a video on this topic, describing how this function can be achieved with jelly-bean parts.
This circuit has it's flaws and isn't exactly very (noob-) user friendly.
While looking for something a bit more practical and "advanced", I came across the Henry HR810:
https://www.aliexpress.com/item/6A-DC-3V-3-3V-3-7V-5V-Electronic-Switch-Latch-Bistable-Self-locking-Trigger-Board/32795061369.htmlThe module works great.
Sadly I cannot find a way to purchase the IC cheaply without the mosfet etc.
Other requirements:- low voltage operation (battery power, singe cell Li-Ion)
- low quiescent current / low power consumption
- low price
(Aliexpress would be good because of the usually free shipping)!
Less important- maybe even a built-in mosfet
- reasonably large footprint, maybe even "DIP-friendly"
I am not asking for the "perfect solution" and am very happy about simple hints and general ideas as to which components could be used.
When searching the internet for suitable parts, I came across several Ti parts which weren't available on Aliexpress. Digikey has them (TPS3422) but I'd have to pay shipping...
Thanks in advance!
