Hi I have a Class D bass amplifier triggering overcurrent detection on certain notes (predominantly D3 = 147Hz) that must be causing some kind of harmonic resonance with other parts of the circuit maybe the output filtering.
Can anybody help me adjust the overcurrent detection thresholds a bit so as to be less sensitive? ... the interaction of the 2x IC's involved IC9 (TS512ID) & IC15 (LM393) is more complicated than I've seen before, maybe it's just the way it's drawn on the schematic.
VDD+ = +5V
VDD- = -5V
Here is the layout:
