Part Number: TPA3255 Tool/software: Interested in making the simplest possible SE input circuit for a BTL configurated TPA3255, to be used from 60Hz up, with an 6dB input filter. 1: Can input_B be connected directly to ground instead of a capacitor of…
Part Number: TPA3255 Tool/software: Hello，
The customer uses TPA3255 to drive the motor coil. The schematic diagram is shown below. Customer feedback: The chip heats up severely and produces a lot of noise. The motor speed is not sufficient compared…
Part Number: TPA3255 Tool/software: Hi TI,
I have designed a Class D 240W audio amplifier with TPA3255 in PBTL configuration. I have used two test conditions to measure the power dissipation of class D IC as follows
• Case 1
Vin - 52V
Iin - 6.9…
Part Number: TPA3255 Tool/software: Hi Teams,
The customer is using TPA3255 amplifier chips for subwoofers (PBTL mode). Currently, there are about 1500 units produced, and 2pcs of amplifier chips have been burned out and the damage is basically the same…
Hi Ramsey,
The customer and LC temperature are still very high，
Can you clarify what is meant by "When removed and powered on again"? what exactly is removed in this case?
-----The customer removed TPA3255 and re welded it.
I have advised the…
Part Number: TPA3255 Tool/software: Dears,
A device was used on the customer's site for about a month and experienced damage to the amplifier chip. After measurement, it was found that the OTA-A pin was broken down to GND. The VBUS+ of the amplifier…
Part Number: TPA3255 Tool/software: Hello,
I am working on a design using the TPA3255 class D audio amp IC. My design is based on the TPA3255EVM configured as 4 SE channels. My design is only using channel A and B, would I still need he large 4700uf…
Part Number: TPA3255 Tool/software: Hi Team
I need below clarification on TPA3255 EVM Board and ATS-Quats Heatsink assembly
1. How is the assembly of TPA3255 & EVM Board heatsink is assembled , Is there we have any Airgap ? or its face to face connection…
Hi Tien Nguyen,
regarding the current sensing ,you can refer to the datasheet 9.4.1.1:
"9.4.1.1 Overload and Short Circuit Current Protection"
"TPA3255 has fast reacting current sensors with a programmable trip threshold (OC threshold) on all…
