The S-80851CLY-Z2-U is a Voltage Supervisor IC from Seiko Instruments with multiple functions, including reset generation, voltage detection, power on reset (POR), and low power reset functions. It is a highly integrated circuit that can be used in various applications, including personal computers, automotive, and telecommunications. In this article, we will discuss in detail the application field and working principle of the S-80851CLY-Z2-U used for PMIC - Supervisors.

The S-80851CLY-Z2-U is a single-chip voltage supervisor that offers high integration, low power consumption and reliable reset generation. Its main purpose is to generate system reset signals when the input voltage level is outside the setting range, or when the voltage drops below the low voltage warning threshold. It also offers port-selectable reset polarity output and reset magnetic latching capability. This means that the system will not reset unless the voltage deviates beyond the safety range, which makes it suitable for use in safety-critical applications.

The S-80851CLY-Z2-U can be used to provide reset protection in a variety of different situations. It can monitor input line voltages of up to five different power rails in order to detect low voltage warning (LVWR) and reset conditions. It also has an input pull-down resistor to ensure proper reset signaling. In addition, its reset output polarity can be inverted if desired, allowing the user to easily adjust the reset characteristics.

The S-80851CLY-Z2-U has a wide range of applications, from personal computers to automotive, telecommunications and other industrial control equipment. For example, it can be used to monitor system voltage in automotive applications such as vehicular electronics, electric powertrain control systems, and engine control systems. In addition, it can be used to generate reset signals in home appliances such as air conditioners and refrigerators, as well as in telecommunication systems such as GPS tracking and cellular base station communication systems.

The S-80851CLY-Z2-U works by constantly monitoring the input voltage, and if the voltage exceeds or falls below the preset thresholds, it will generate a reset signal. The reset signal is a square wave signal with a specific frequency, amplitude and duration, which is then passed to the reset monitoring device. The reset monitoring device will then detect the signal and trigger the reset of the system.

The S-80851CLY-Z2-U is a highly integrated voltage supervisor that can be used for various purposes. Its reset generation capabilities are reliable and highly accurate, making it suitable for use in a variety of applications. Additionally, its low power consumption and integrated functions make it an ideal choice for many applications.
