Hi all,
I have a circuit in which a MOSFET (irf510A) is being driven by a 2n2222 transisitor. The MOSFET is getting very very hot. The supply voltages are 32V for the Mosfet with a current load of 2.8A. This is a simple unipolar stepper motor driver which takes pulse input from the parallel port.
I want to ultimately have a pulse frequency of 25KHz. How do I check if the MOSFET can handle this type of a frequency. ALSO more importantly how can I check if the MOSFET is performing to its specs if I do not have a scope to test its switching functionality.
Appreciate the help
regards
