i use dspic micro and ir2104 to drive half bridge mosfet
i use 12 volt , 150 watt switching power supply and lm2576 3.3 for dspic.
when the mosfet load is 10 watt no problem but when the load is 50 watt ,micro Continuous
reset and power up.the mosfet is irfz44
i pullup mclr pin with 10k resistor and put 100 nf cap for each vcc gnd.
i think when the mosfet goes on the high load, generate noise and the mclr pin reset.
because i dont have Voltage drop on vcc of micro but when i see gnd line with oscop its noisy when the micro is in reset
how to solve problem?
i separate gnd and vcc of dspic with 2 ferrite bead and add 100 nf cap series with mclr pin but yet dspic Continuous in reset
