Alarms, buzzers, and sirens play an important role in various environments and provide the necessary warning signals to alert individuals of possible dangers. The SCE120MA3SR4B is an electronic driver circuit that extracts the triggering voltage pulses from an automotive reverse alarm system or a security system for a residential or commercial building and amplifies them according to the characteristics of the integrated piezoelectric transducer. This article examines the SCE120MA3SR4B application field and working principle.
The SCE120MA3SR4B is designed to integrate into the existing alarm system in order to provide a louder and more powerful sound compared to the conventional piezoelectric security buzzers. This electronic driver circuit is a complete solution for driving piezo transducers without the need for additional components or circuitry. It is a single-chip solution that can drive both audible alarms and alarm-in-progress sound sources. It can be used to provide warning sound levels up to a maximum of 100dB and can be connected to a variety of piezo transducers, making it suitable for both residential and commercial alarm applications.
From a functional perspective, the SCE120MA3SR4B is divided into five main sections: an oscillator section, a comparator section, an audio section, a power supply section, and a general control circuit. The oscillator section is responsible for generating the triggering voltage pulses by converting the input voltage signal into a series of sinusoidal waves. The generated pulses are then fed into the comparator section, which converts the sinusoidal waves into square-wave pulses. The audio section is responsible for amplifying the pulses in order to improve their sound level. The power supply section is composed of a voltage regulator, a rectifier, and a filter to provide power to the oscillator, comparator, and audio sections. Finally, the general control circuit is responsible for controlling the device’s operation, including its start-up and shutdown.
The SCE120MA3SR4B is compatible with a variety of piezo transducers, providing up to 100dB of warning sound at a frequency of up to 15kHz. It is a single-chip solution that can be used to build an alarm system without the need for additional components or circuitry. The device can be used in a wide range of applications, including automotive reverse alarms, security alarm systems, medical alert systems, and residential smoke and fire alarm systems. Additionally, the device’s low power consumption and integrated rectifier and filter make it suitable for a variety of energy saving applications as well.
In summary, the SCE120MA3SR4B is an electronic driver circuit designed specifically for use in automotive reverse alarms and security systems. It is designed to extract the triggering voltage pulses from the alarm system and amplify them in order to improve their sound level. The device contains an oscillator section, a comparator section, an audio section, a power supply section, and a general control circuit. It is a single-chip solution that can be used to provide warning sound levels of up to 100dB. Additionally, it is compatible with a variety of piezo transducers and is suitable for a variety of applications, including automotive reverse alarms, security alarm systems, medical alert systems, and residential smoke and fire alarm systems.
