Lithium batts should be under surveillance either charging or discharging.

The little circuits are supposed to work in either case, not allowing overcharge or flat discharge the batteries. The...

You got yourself 2 points so far with naughty thoughts! :wink:

Roger,

The important specs is dependent on the application.

For example, if you drive the MosFet from a logic level chip, say a MCU, then you want the Vgs to be as low as possible for the...

Because according to Electrical Specs, the FVR may be from -8% to +6% for example on 16F1827.

I would not trust this to charge a LiPo battery at all!

Roger, the minus Vgth is correct. Consider it a different visual angle!

In P-channel or PNP transistor the voltages are the opposite of the N-channel or NPN transistors. Means that the voltage og...

FVR is not at all accurate, so that 4.25... I doubt you are safe.
