PMIC - Supervisors: S-80824KNY-Z2-U application field and working principle

PMIC - Supervisors: Power Management IC Supervisors (PMICs) are integrated circuits that offer a comprehensive power management solution for embedded microprocessor systems. These integrated circuits monitor the power supply and reset the microprocessor system in case of an over voltage/under voltage, over current or short circuit condition. The advanced PMIC Supervisors, such as the S-80824KNY-Z2-U, perform more than just monitoring and resetting.

The S-80824KNY-Z2-U is a PMIC supervisor with an Enhanced-Reset (ER) circuit. The main function of the ER circuit is to reset the systemcontroller and peripherals while enforcing a safe timing sequence. This is achieved by providing active voltage and frequency scaling control, allowing the microprocessor core to assume a desired voltage and frequency level. The ER circuit also monitors the microprocessor’s core temperature and can reset the system in reaction to an overheating condition. Thus, the ER circuit provides a reliable and fast power reset to the microprocessor core.

Application Field of S-80824KNY-Z2-U

The S-80824KNY-Z2-U features a protection circuitry which prevents system overshoot and undershoot conditions to protect the control cores from catastrophic damages. This protection circuitry can detect any potential overvoltage, undervoltage, overcurrent or short circuit condition and reset the system based on an internal look-up table. This feature boosts the performance of the microprocessor systems and increases their lifetime.

Due to its low power consumption and space savings, the S-80824KNY-Z2-U is ideal for industrial and consumer applications. Its simple pin-to-pin and software compatible design guarantees easy system-level integration. Additionally, the S-80824KNY-Z2-U comes with a low quiescent current of only 250nA, making it suitable for battery operated systems.

Working Principle of S-80824KNY-Z2-U

The S-80824KNY-Z2-U uses an Enhanced-Reset (ER) circuit to reset the systemcontroller and peripherals while enforcing a safe timing sequence.
