Beijing Dongwei Century Technology Co., Ltd. announced the successful development of the stereo amplifier and speaker protection IC (enhanced) - EMT1237B, and has begun full supply in the near future. The chip is an integrated circuit designed to protect stereo amplifiers and speakers. The relay controls the connection status of the amplifier and the speaker, achieving high system reliability and improved system performance.

The chip EMT1237B is manufactured by Bipolar process and packaged in the form of SIP8L. The circuit can detect the DC drift of the amplifier output through only one pin. When the DC drift exceeds the chip protection set value, the circuit will disconnect the amplifier and the speaker through the control relay. Ensure that the coil does not heat up due to excessive DC output, thus protecting the amplifier and the speaker. The circuit also has a delay start and shutdown detection function, which avoids the opening and closing noise.
This EMT1237B chip has greatly improved the detection sensitivity and reaction time, and its product performance is better than similar ICs at home and abroad; for more detailed technical parameters, please refer to the description and Data Sheet of this product on the website of Beijing Dongwei Company.
Beijing Dongwei has developed a comprehensive product line for consumer electronics, mobile terminals, and security testing. As the latest product in its audio series, EMT1237B is another independent innovation that responds to the needs of the industry. As a local chip design company, Beijing Dongwei will continue to maintain the competitive advantages of cost-effective and stable supply of domestically produced innovative products.
