Power management integrated circuits (PMICs) are extremely important components in modern electronic systems, as they are responsible for supplying power to the electronic system, ensuring components function and regulating the power levels. The S-80934CNMC-G84T2U is one of the many PMICs, categorised into Supervisors, and is used to accurately monitor and control power in a variety of applications. This article aims to provide an overview of its application fields, as well as its working principle.

The S-80934CNMC-G84T2U is a low-power supervisor from Seiko Instruments that provides three different supervisor functions: power supply monitoring, manual reset, and power on reset. This device is best suited for portable applications such as tablet PCs, handheld gaming consoles, and mobile phones. As such, it is essential for the device to have a low operating current, quick response time, and temperature-stable operation.

The S-80934CNMC-G84T2U achieves this both through its low operating current of 1.1mA (typical) and an integrated logic block with two digital output pins and one analog output pin. The digital output pins have a logic level of 0 when the power supply exceeds the threshold of 3.0V and a logic level of 1 when the power supply drops below it. This provides quick response times and temperature stability for the device. Additionally, the analog output pin is configured to output the voltage of the power supply and provides an accurate indication of the power supply voltage for any given application.

The S-80934CNMC-G84T2U is a versatile device capable of being used in a range of applications. It is most commonly used in low power consumer applications, such as data acquisition systems, medical equipment, smart meters, or home automation. Additionally, the device can also be used in applications such as digital cameras and the automotive industry, where its accurate power supply voltage monitoring and low operating current are required.

The working principle of the S-80934CNMC-G84T2U is quite simple. The device integrates two digital output pins and one analog output pin. The two digital pins are configured to output a Logic Level 0 when the power supply exceeds the threshold of 3V and a Logic Level 1 when the power supply drops below it. This provides quick response times and temperature stability for the device. The analog pin is configured to output the voltage of the power supply, providing an accurate indication of the power supply voltage for any given application.

The S-80934CNMC-G84T2U is an innovative PMIC offering from Seiko Instruments, making advances in miniaturisation, power consumption and accuracy that have enabled it to become a popular choice in portable and low-power applications. Its ability to accurately monitor and control power makes for an ideal choice for applications where low-power consumption and accurate power supply voltage measurements are essential.
