Dear all,
Im brand new here so be kind, I have a couple of questions and some help needed with a mosfet circuit im building for my airsoft rifles.
basically the system is an Active braking circuit.
I have been supplied some schematics from a well known supplier of these products but it seems wrong (works when constructed but im not sure if the braking circuit is working correctly).
Also i have a few questions about the Fet's im choosing to use.
So here is the details.
**broken link removed**
the circuit im using is the top SW-AB system.
Ignore the mosfet part numbers on the diagram as im using these in replacement:
P channel FET - IRF5210S replaced with SPP80P06P
N channel FET - IRL1404ZS replaced with STP75NF75
the capacitor part number is 222206036109
the resistors are carbon film
100R = CFR16J100R (0.25W)
220R = CFR100J220R (1W)
4.7K = CFR100J4K7 (1W)
the TVS diode is shown as a bi-directional device but this is an DC circuit so that is another part that is confusing myself.
Would someone be kind enough to check the circuit and tell me if it would activly brake the motor. Basically in airsoft rifles single shot tends to overrun on higher voltages or miss trigger pulls, this system completes the cycle and leaves the spring uncocked because it does not overspin.
any more information needed ask and i will try to supply as much as i can.
Regards
Richard
