Hi
I’m looking for shemmatic for fet+1 (lfpak) driver, attiny25, e switch.
Thx
Maybe this thread will be helpful:
Can you be more specific? Are you looking for schematics of a specific driver, do you want to build one yourself or is it just about knowing how a FET+1 driver works in principle?
Yes, is dd fet+1 driver, i think emisar d1s have the same?
Answering with “yes” to a multiple choice question is not really helpful. What exactly do you want to know or what do you want to do?
…custom shape of this driver. Have you shemmatic maybe?
What type is D1, schottky or zener?
If zener, is it in the circuit correctly?
If schottky, what is its purpose?
D1 schottky for RPP
Its for D4s or GTmini firmware.

Thank you!
Without pin3 schemmatic is for d1s?
Yes. D4, D1, D1s.
How I can simple limit current on this shemmatic?
Thinner wires. But current will vary depending on battery performance, contact resistance etc.
Resistor in serie with led?
No simple way.
