About Photovoltaic Energy StorageI wanted to add to my power supply circuit an undervoltage lockout based on this but with different components. The circuit looks like this: simulate this circuit – Schematic created using $begingroup$ I have turned the Pmos and the circuit works so thanks, but now the voltage needs to up to at least 3.6V in order for the output to return at …
About Photovoltaic Energy StorageWhen the undervoltage protection kicks in, the battery gets disconnected and stops supplying power to the boost converter. This causes the battery voltage to rise slightly and the undervoltage circuit will no longer detect an udervoltage and it reconnects the battery again which causes its voltage to drop and the circuit to cutoff power.

About Photovoltaic Energy StorageI''ve recently included Lithium-Ion batteries in one of my projects and for the protection I have been relying on a battery pack with an internal protection circuit uptil now. Since I want to be able to use Li-Polymer pouches which typically don''t come with this internal protection I want to include on-PCB protection.
About Photovoltaic Energy StorageI was thinking of buying for the first tests a 2s or 3s commercial lithium battery pack with protection (short circuit, overvoltage, undervoltage per cell,…) already integrated (unspecified IC). I am unsure whether that protection circuit might interfere with the normal operation (measurement accuracy,…) of the bq40z50, invalidating the test.
