Working Principle

The APX810S05-26SA-7 employs various systems working together to ensure power voltage surge protection and to guarantee the reliability of any integrated circuits it is supervising.

To begin, the watchdog system is employed as a safety measure against suddenly occurring faults, ensuring that operated circuits function properly during steady state and watchdog reset operations, even in cases of microprocessor fault. This includes the reset CPU’s, resetting the connected circuitry and reset delay method.

The APX810S05-26SA-7 also features a window voltage detection system, which uses a voltage input pin and a reference voltage pin in order to monitor a voltage range, warning the user when the set voltage range has been exceeded, by sending a reset signal.

The APX810S05-26SA-7 has two pulse width adjust pins, designed for adjusting the reset pulse width and reset delay pulse width. By varying these two pulse widths, the user can optimize the operating conditions of any associated integrated circuit.

The timer circuit in the APX810S05-26SA-7 helps the user adjust the reset and recovery timing independently, resetting the operated circuit when it’s malfunctioning, and then start to recover the original operating condition.

The APX810S05-26SA-7 has a temperature detection system to protect the connected circuits from faults due to the temperature rising above a set value. This was designed to prevent any internal circuits from overheating, damaging other parts and endangering users.

The APX810S05-26SA-7 is built-in with a highly accurate voltage detector along with a low voltage detection circuit. This combination detects changes in voltage values and sends reset signals to the affected circuits in order to stop downstream damage and prevent any disruption of electronic flow.

Conclusion

In conclusion, the APX810S05-26SA-7 is a highly reliable PMIC Supervisor IC with an array of safeguards and multiple functions, helping to ensure that any associated integrated circuit is functioning efficiently and securely. With its versatile applications and comprehensive working principles, the APX810S05-26SA-7 is a powerful, reliable and much-needed device in order to guarantee safe operations of integrated circuits from power voltage surge.
