earthquake phd2

DREW028 · 28th May 2012, 06:01 PM

I pulled all the PS transistors and I'm getting 13v on the gates. Ic5 and ic8 are defaced. I do have a 200dhc still that has a sg3525an in ic5. If they are the same chip here are the readings. Do they seem right? What could ic8 be?

Ic5
Pin 1: .099
Pin 2: 5.1
Pin 3: .018
Pin 4: .119
Pin 5: 2.06
Pin 6: 3.88
Pin 7: 2.06
Pin 8: 4.83
Pin 9: 5.7
Pin 10: .112
Pin 11: 6.38
Pin 12: .015
Pin 13: 13.51
Pin 14: 6.38
Pin 15: 13.51
Pin 16: 5.1

Correct me if I'm worng please. As far as the pin lay out the only difference is the #6 pin. I've been trying for figure which ic this is. Pin 6 of ic8 connects to Pina 15 and 13 of ic5. Would this make it the tc4424?

Ic8 readings

Pin1: 0
Pin2: 6.3 (pulse)
Pin3: .012
Pin4: 6.37(pulse)
Pin5: 12.6
Pin6: 13.51
Pin7: 13.27
Pin8: 0

Those two ICs are the same other than the manufacturer.
