PMIC (Power Management Integrated Circuits) are integrated circuits designed for managing the power requirements of electronic systems. Supervisors are specific ICs that usually monitor other handheld power systems. An example of this is S-80141ALPF-JA2TFG. This IC is designed to provide protection to a system’s power supplies and protect against damage caused by overvoltage and short circuits. In this article, we will discuss the application field and working principle of this IC.

Application Field

The S-80141ALPF-JA2TFG is a single channel supervisor IC that is suitable for a range of applications including power and fault protection systems, microprocessor power supply monitoring, system reset controllers, and battery management systems. It is also suitable for other power system protection applications that require a monitor with overvoltage protection (OVP) and undervoltage protection (UVP).

The S-80141ALPF-JA2TFG has an operating temperature range of -40°C to +85°C, and is able to withstand voltages up to 24 V. It also has a maximum operating current of 10mA, which makes it well suited for low power applications. The S-80141ALPF-JA2TFG is available in a small, four pin SOIC-8 or DFN-8 package, making it an ideal choice for power system design.

Working Principle

The S-80141ALPF-JA2TFG monitors the voltage of its supply voltage, and provide both overvoltage and undervoltage protection. It operates in three different modes: Normal, Fault, and TRI-STATE. In Normal mode, the IC monitors both voltage high and voltage low levels, and activates a TRI-STATE output signal when either voltage limits are exceeded. The output signal is then used by the system as a reset signal or warning when either undervoltage or overvoltage is detected. The Fault mode is triggered when the TRI-STATE output signal is enabled, meaning that the voltage levels are outside of predetermined limits. The Fault mode will disable the TRI-STATE output signal, which can be used to trigger other system protection mechanisms. The TRI-STATE mode is the third mode, and is used to disable the voltage monitoring circuit and return the output signal to its low state.

The S-80141ALPF-JA2TFG has two separate monitor current options, one for high voltage levels and one for low voltage levels. This allows for easy adjustment of the voltage levels being monitored, enabling the designer to customize voltage level settings for the specific application. In addition, the IC can be configured to respond to either a positive or negative overvoltage event, which is used in many applications that require power supply protection. The S-80141ALPF-JA2TFG also offers a wide range of reset delay times, ranging from 0-5ms, to 0-500ms, depending on the application.

Conclusion

The S-80141ALPF-JA2TFG is a single channel supervisor IC designed for a wide range of power system protection applications. It is able to monitor high and low voltage levels, and activate a TRI-STATE output signal when either voltage levels are exceeded. The IC also offers the ability to configure a positive or negative overvoltage event, and offers a range of reset delay times. This makes it an ideal choice for many power system design requirements.
