Part Number: TPA3244
I created the below PCB. IT is designed as 1x BTL, 2x SE with option to make 2x BTL. When I power it up I hear a hum that intensifies until it cuts out.
Power rails remain stable. Reset is floating. Fault pin remains HIGH, even…
That external circuit would not work as the internal pin is different, so it would not work.
The difference between cmute and reset is that while they both initiate a ramp down sequence of the outputs, and the output FETs go into a Hi…
Part Number: TPA3244 We designed amplifier board ( in single pcb there are 3 amplifier units ) using TPA3244.
It work only for 1-3 minutes Fault LED light up and amplifier stop working. ICs are getting hot.
What is strange is when I touch the top left…
