Hi,
I have a PIC16f877A controlling the DC speed motor.
The motor is basically 12V motor rating of 8W(around 600mA).Actually it is a submersible water pump which commonly used in Aquarium.
The mosfet that I'm using is K1300.
When i ask the electronic shop for IRLZ14, they didnt have, so they just find
a replacement part number from the book which is K1300.
When running the circuit,It takes few second for the motor to actually start pump the water and
the MOSFET get quite hot which is impossible for me
to touch after around 10 seconds. It is a T0-220 Package. Im running at 5Khz.
I'm from Malaysia, getting some other model MOSFET will be hard.
is it the wrong mosfet that im using ? or thats something wrong with my circuit I uploaded my schematic below. Or is it the gate-voltage(4.5V) for the K1300 is not enough and therefore produce so much heat.
Thanks and Appreciate
