Hai,
Can Anyone please help me!!
I am designing a 4V lead acid battery charger using a PIC MCU.
the charger section is ok what my problem is
i have used a IRFZ44 MOSFET to turn the LED load on and off.
I want turn off the load when the battery is discharged to ~3V.
the circuit diagram is attached.
while i turn on the MOSFET i have a voltage drop of more than 1V. ie when battrey voltage 4V i get only 3V for my load even when it is unloaded.
what should i do to decease the drop voltage??
Please help!! :-(
