Hi All,
Can anyone figure out why 555 timer output is not coming as per expected ?
The output should be 10V peak to peak but it is getting loaded with mosfet gate charge.
I want to drive dc motor rated 18V @ 15A.
The idea here to give motor soft start using PWM signal with minimum duty cycle with frequency e.g. 6.8KHz, 16KHz.
I want to give motor soft start for 1 sec before running with 100% duty cycle.
I was trying to implement using discrete components, may be i also need some circuit to drive mosfet for after 1sec with 10V dc not pwm.
Any recommendation on the same is highly appreciable.
Thanks !!
