Do you need a MOSFET for a lipo?
Do I need a mosfet? Besides cost and labor, there are no downsides to using a mosfet. You will get better performance and more reliability no matter which you choose and no matter what battery you are using. If you are using an 11.1 lipo battery, then it is almost mandatory so you do not burn out your trigger contacts.
Is MOSFET needed?
There are several reasons for needing MOSFET drivers: Drive current – MOSFETs can have very high gate capacitance. For example, the IRF530NS from International Rectifier is a 90mW device which can withstand 17A continuous drain current at 100V and has 920pF of input capacitance.
Do you need a MOSFET for a LiPo battery?
No, you don’t need it. It’s just a recommendation. I’ve been using an 11.1v high discharge brick of a Lipo battery for about 2years now with no problems. The mosfet basically minimizes the carbon that builds up on your trigger contacts.
What is the lockout voltage for a Li ion battery?
For a 0.4% overall accurate system, the lockout voltage would be at 3.088V or at 3.112V, more than twelve times better accuracy and optimally achieving the highest capacity. Furthermore, the load is kept disconnected with only 4.5µA to the protection circuit. Thus, the protection circuit works by preventing deep discharge of the battery.
Can a power MOSFET block current in both directions?
As a result, a power MOSFET can block current only in one direction. The switch in the battery protection circuit has to block current in both directions: charging and discharging. That’s why there are two opposing MOSFETs in series: one for each direction. One FET is for blocking charging and the other is for blocking discharging.
Why are there two MOSFETs in the battery protection circuit?
The switch in the battery protection circuit has to block current in both directions: charging and discharging. That’s why there are two opposing MOSFETs in series: one for each direction. One FET is for blocking charging and the other is for blocking discharging. This allows 3 modes of operation: Charging, Discharging & Sleep.
