PMIC - Supervisors: X4165P-2.7A Application Field and Working Principle

Power management integrated circuit (PMIC) supervisors are an important component of many industrial and consumer electronics systems. PMICs are used as programmable voltage and current regulators that provide reliable power for a wide array of applications.

X4165P-2.7A is a voltage supervisor and reset generator IC (integrated circuit) specifically designed for the protection of microprocessors, 16-bit microcontrollers and system-on-chip (SoC) solutions. With its watchdog timer and a robust reset circuit, it is capable of monitoring voltage levels and triggering a reset if a given threshold is exceeded.

Application field

The X4165P-2.7A voltage supervisor is designed for a wide range of industrial and consumer applications, such as motion control, computer servers, medical and automotive systems. It can also be used in a variety of portable devices, such as digital cameras and mobile phones, where precision voltage regulation is essential for component longevity.

In addition, X4165P-2.7A utilises low power operation, making it ideal for battery-powered portable devices. With its built-in 90% to 110% reset threshold and active low RESET output, it ensures proper reset at all times, even in the presence of power glitches.

Working Principle

The main functionality of the X4165P-2.7A is to monitor the input voltage level and reset the system when it reaches a certain threshold. It can be configured to auto-reset once the input voltage passes a set threshold, and manually reset via a RESET control pin.

The X4165P-2.7A also provides a watchdog timer that can be used to detect system failure or fault conditions. It operates as a frequency-divider circuit with an adjustable pulse frequency range of 1 Hz to 1 kHz, allowing it to detect system stalls or fault conditions (e.g. stuck loops). In case of a system failure, the X4165P-2.7A will automatically reset the system once the timer reaches a certain threshold.

The X4165P-2.7A also includes a built-in power-on reset, allowing the IC to be powered up without any additional external circuitry. It can be used to reset any microcontroller or SoC system, providing reliable, robust protection against unexpected power glitches or voltage surges.

X4165P-2.7A is a low dropout linear voltage regulator designed for a wide range of industrial and consumer applications, providing the user with reliable regulation and protection for their system.

Conclusion

X4165P-2.7A is a voltage supervisor and reset generator IC designed for a wide range of industrial and consumer applications. It provides reliable power regulation and protection for microprocessors, 16-bit microcontrollers and system-on-chip solutions. It also features a watchdog timer and a built-in power on reset to detect system stalls or fault conditions. With its robust reset circuit and low-power operation, X4165P-2.7A is a great choice for reliable voltage regulation and protection.
