PMIC - Supervisors
S-80141ALPF-JA2TFU is a supervisor for micro-power management ICs that provides system reset protection and other management functions, consisting of a power management unit (PMU) and a reset monitoring unit (RMU). These ICs provide high-performance, low-power control integral to many electronic designs.
Application Field
Typically, microprocessors or microcontrollers found in consumer devices such as TVs, video game consoles, and cell phones require a power reset signal during operations to ensure their proper functioning. S-80141ALPF-JA2TFU provides the reset signal that these microcontrollers need to maintain their proper operations. It also resets the processor when it enters standby modes, power up or down, begin or end operation modes, and a wide variety of other scenarios.
Working Principle
S-80141ALPF-JA2TFU has two main parts: a power management unit (PMU) and a reset monitoring unit (RMU). The PMU is responsible for supplying power to the microcontroller or processor, while the RMU provides a reset signal during operations. This reset signal is triggered when the PMU detects a power event, such as a drop in voltage, interruption or application of power, or power on/off state, among others. When this occurs, the RMU induces a low-impedance reset signal that is communicated to the processor to ensure smooth operations. The RMU also monitors the power and reset signals continuously, so that if any abnormalities are detected, the processor restarts properly.
The ICs through which the RMU operates have extreme accuracy for measuring the voltage, and therefore can control the reset signal with very precise timing. This ensures that the reset signal is triggered before the microcontroller or processor can enter a critical failure state. Lastly, the ICs also provide a level of protection against power surges and/or drops, providing a very reliable reset signal.
In turn, this all provides a high level of quality assurance, ensuring that microcontrollers and processors remain stable and do not become prone to errors. S-80141ALPF-JA2TFU is an invaluable component of many types of electronic devices, guaranteeing optimal performance and quality.
