DIYfan Speaker protection with uPC1237
Simple Speaker Protection Circuit for Power Amplifiers with Balanced Outputs XEN Audio October 2013 Introduction If one search on the internet, one would find tons of speaker protection circuits for single-ended power amplifiers. There are also simple-to-use ICs designed for the purpose, like uPC1237 or TA7317, but
Speaker Protection Board Circuit Diagram Soldering Mind
A speaker protection and muting circuit is installed between a DC coupled audio power amplifier output and the speaker. Its main purpose is to disconnect the speakers as soon as a large DC voltage that can damage the speaker is present at the output of the amplifier. This can happen when the amplifier is malfunctioning.
Speaker Protection Circuit (Connexelectronic) Hifime Audio
The speaker protection circuit detects the DC voltage at the amplifier output and disconnects the speaker. The DC voltage detection level of the protection circuit is very low (0.7…1V) so that the speaker is protected from being exposed to high voltage.

$99 The Guardian-86 is a high-end protection circuit designed to protect speakers against two common ways that power amplifiers can misbehave: Sharp voltage transients on power-up and power-down, resulting in annoying clicks and pops in the speakers.
Speaker protection circuit
Speaker Protection Circuit can be powered with AC voltage in range of 8 to 12V AC, 50 or 60Hz and requires about 40mA for proper operation. This is a very small current which can be obtained from an auxiliary winding of any transformer.
How to make Speaker Protector Circuit with DC Protection Speaker protector diagram YouTube
Feb 7, 2020. #3. A protection circuit monitors the output offset voltage, and will usually disconnect the speakers if the offset voltage exceeds about 1 volt. In addition they usually monitor output transistor currents and will 'trip' if the current exceeds a safe value.

Loudspeaker DC protection is always something of a mixed bag. Units such as Project 33 are well behaved and will offer a high level of protection for the speaker. Should the amplifier fail, the most common failure mode is for an output device to short-circuit, causing the output to swing to one supply rail or the other.

uPC1237 is a well known IC used for protecting the speakers form DC as well as amplifiers from over current. Almost any Sony amplifier starting from the lower range and right up to the higher-end ES series are using this chip. So I thought was a good idea to make a stand alone module which could be used by the DIY community.
