Hello, "PNP transistor as a SELECT SWITCH" is it possible?
I want control with MCU (atmega328p)
24v -> LM7805(regulator) -> MCU -> a. 24v Relay (700mW)
-> b. 24v motor (3A)
-> c. 24v motor (1A)
PNP (bc327)
a.700mW -> 70mW
b.
c.24V ->>>> 15v
so selecting 'a' or 'b' or 'c'
'a' worked. but 'b', 'c' I think i have to use more high Armps PNP TR.
so i want to ask like
1. " 'is these 'b', 'c' are possible? not using relay "
2. If i using high Armps PNP TR, for low temp. Do i have to use maximum current over 10A TR?
is this cal, if i want change pnp tr
it would be
Id2 = 9 Armps
Rds under 0.055
Rthj-a Under 50
is it right?
