SR2PARU Integrated Circuits (ICs)

Supervisors are an important component of power management integrated circuits (PMIC). They are responsible for ensuring the reliable operation of the system, controlling the power supply when required and providing accurate time reference signals. The SR2PARU supervisor is a PMIC that provides many features including system reset, system power control, precision timing and temperature measurements.

The Application Field of SR2PARU

The SR2PARU is a multipurpose system reset supervisor that is ideal for use in systems that require an efficient and accurate system reset. It is suitable for use in telecommunications, automotive, medical, industrial, and consumer applications that need reliable system reset operation.

The SR2PARU also provides comprehensive system supervision functions including voltage and temperature monitoring capability. The device supports a range of supply and monitoring voltages from 1.2V to 5V and is designed to operate in temperatures ranging from -40°C to +85°C. This makes it ideal for applications in extreme environments, such as automotive and medical systems.

The Working Principle Of SR2PARU

The SR2PARU is a multifunction device that uses a state machine to provide several reset functions, including power-on reset, system idle reset, and watchdog timer reset. When the device receives an appropriate command, it changes its state, allowing the system to be reset.

The SR2PARU also provides an adjustable voltage monitoring function that allows the system to detect out-of-range voltages, such as too low or too high. When an out-of-range voltage is detected, the device triggers a reset operation.

The SR2PARU also offers a power-fail reset and a temperature trip reset, which allows the system to detect and respond to changes in system temperature. When the temperature threshold is exceeded, the device triggers a reset operation.

The SR2PARU provides a wide range of features to enhance system reliability and performance. These features include power-on reset generator with adjustable delay time, programmable reset threshold, adjustable supply voltage monitoring and adjustable temperature trip reset. The device also features power-fail reset, watchdog timer reset and system idle reset with adjustable timeout.

Conclusion

The SR2PARU is a PMIC that provides a comprehensive range of features to provide reliable system reset operations. It is suitable for use in a variety of applications and offers adjustable settings for reset threshold, temperature trip reset, and supply voltage monitoring. This makes it a reliable and efficient choice for system supervisors.
