decuppling caps are right under the Vcc Pins and bottom layer is used as ground power plane

Hi
i tested today with 24V bulbs ( Risitive load )
and the driver did not turn off with them.

but with the motor alone or motor with blubs in parallel the driver turns off


Any info will really help

hi, I tested with 12V blubs and it des not seems to stop. at lest till the blubs burnt out. but it did happen ones when i turn on it for the first time, but after i reset not happen. ill test with 24V blub tomorrow. last time i tested i noticed if i connect and disconnect the terminals ( causing a s...

Any idea what is the issue with ground cos one before i tested with resistive load and it did happen.

any ideas what caould be the issue

I did and attached is the DSO plot

Im using DSPIC33EP512MC806 to drive a Stepper motor, Schematics is attached below. driver works ok at low voltages ( 15 or less ) and low currents ( 2A or less ) at higher currents or voltages the PWM module resets randomly. can some one tell me what is the issue. design worked before with SM72295 d...
