Hello Yamamoto-san, The protections that you mentioned are part of the TPA31110, which detect a particular fault and then essentially shut-down the output based on a Hi-Z state, which is why you do not see the current. Section 7.1 covers the details with…
Part Number: TPA3110D2-Q1 Other Parts Discussed in Thread: TPA3110D2 Hi~
Customer trying to evaluate TPA3110D2 and they want to measure power stage return current.
Based on block diagram, there are 4 PGND path from both L and R channels.
In pin…
Part Number: TPA3110D2-Q1 Dear all,
Could you teach me how to think about short circuit protection?
>Question 1,
Can we define the short circuit protection as current value?
I think that this short circuit protection is defined as energy amount…
Part Number: TPA3110D2-Q1 Other Parts Discussed in Thread: TPA3110D2 Dear all,
Could you teach me how max current and power this device can output?
If you can not define the limit of current and power, can you define safe operation range? How current…
Other Parts Discussed in Thread: TPA3110D2-Q1 Hi champs,
My customer asked following questions regarding to TPA3110D2-Q1.
Can you confirm below?
(1) EMI suppression
Should Beads filter (or inductor) and capacitor be placed closed to output port…
Yamamoto-san,
I have not seen the internal design for this feature, so I am speculating as to how the LDO voltage is changed. If the reference is changed, then changing a resistor somewhere would probably be the easiest method.
When designing with…
Part Number: TPA3110D2-Q1 Dear all,
Could you teach me about title?
At 16V/14V/11V/9V, how does the temperature characteristics of GVDD change?
You mentioned that GVDD will change 6.4~7.4V at Vcc=12V/24V at data sheet.
In other words, will…
Other Parts Discussed in Thread: TPA3110D2-Q1 Dear all,
My customer concern whether the back electromotive force from speaker will break TPA3110D2-Q1.
Could you teach me what point should I measure back electromotive force to judge this device will…
Other Parts Discussed in Thread: TPA3110D2-Q1 Dear all,
I would like to know how to detect speaker open condition under using TPA3110D2-Q1.
I know that TPA3110D2-Q1 does not have open detection.
Are there other better way to detect speaker open…
