1. What is a monitoring IC?
A monitoring IC is an integrated circuit used to ensure the correct operation of a microprocessor-based system. It mainly monitors during power-on and shutdown, and when entering or exiting shutdown or sleep mode to ensure the stability and reliability of the system. Monitoring ICs can provide a variety of functions, including power-on reset, backup battery management, memory write protection, low voltage warning, and software watchdog. Common monitoring ICs include AD8206YRZ, INA194AIDBVR, MAX9938FEUK+, etc. These chips are widely used in various electronic devices to ensure the stable operation of the system.

2. What is PMIC in electronic products?
PMIC (Power Management Integrated Circuit) is a key component dedicated to managing and distributing power in electronic devices. It improves the efficiency and reliability of the power system by integrating multiple power management functions, while reducing the size and cost of the device.
The main functions of PMIC include power supply, battery management, charging management, and power consumption management. It can provide stable power to the main system and manage and control the battery. -
3. What is the difference between PMU and PMIC?
The main difference between PMU and PMIC is that they have different application scenarios and functional positioning. PMU is a power management unit, which is mainly used in portable devices to integrate traditional discrete power management chips to improve efficiency and reduce power consumption. PMIC is a power management integrated circuit, which is mainly used for highly integrated power management solutions, encapsulating multiple output power supplies in one chip to improve efficiency and reduce size.

4. How to test PMIC(Power Management Integrated Circuit)?
The core steps of testing PMIC include observing external features, conducting comprehensive professional testing, and measuring PSRR.
First, observing external features is the first step in testing PMIC. Rationally observe the quality standards of power management chips, including their appearance, logos, etc., to ensure that the chip meets basic quality requirements.
Second, conduct comprehensive professional testing. Select representative specification models and conduct comprehensive tests on the power management chip, including electrical characteristics test, functional test and environmental adaptability test. The electrical characteristics test covers the input voltage range test to ensure that the chip works normally under different input voltages.
Finally, measure the PSRR (power supply rejection ratio). PSRR is an important parameter of PMIC, indicating how stable the input is when the power supply voltage changes. By measuring PSRR, the resistance of PMIC to power supply voltage changes can be evaluated.
