motors browning out PIC

[Charles Linquis]

I have had great success by feeding the PICs VCC (and MCLR) through a low voltage drop Schottky diode. On the PIC side of the diode, I use a 10uF tantalum and several .1uF ceramics.

This has worked well for me in critical military applications controlling hundreds of amps.

Hi Mike,

If you are using MCLR, can you not use it?
If it is a must, what is the resistor on MCLR, 4.7K, 10K?

Also, why not turn off BOD ?


Edit: I have a similar application with heavy DC motors, same PIC as yours. BOD_OFF, MCLR_OFF. No reset whatsoever.
