1. What is PMIC in embedded systems?
PMIC plays a very important role in embedded systems. It is responsible for monitoring and controlling the power status of the system, can manage multiple power rails, and provide functions such as voltage regulation, battery charging, and power sequencing. Through these functions, PMIC ensures stable operation of the system and effective use of power.
Depending on the functions and applications, PMIC can be divided into the following basic categories: linear regulators, switching regulators, battery charging management, DC/DC converters, and multi-phase power management. These categories help meet the diverse needs of different electronic devices for power management.

2. What is a power monitor?
A power monitor is a device used to monitor the power status. It can monitor the voltage, current, temperature and other parameters of the power supply in real time, and issue alarm information in time to help users detect power failures in time and ensure the stable operation of the equipment.
The main functions of the power monitor include:
Improving the reliability and stability of the power system: By monitoring the voltage, current, power, frequency and other parameters of the power system in real time, timely discovering and alarming the power system's faults, abnormalities, overloads, short circuits, etc., to prevent power system failures from causing equipment downtime or data loss.
Optimizing the operating efficiency of the power system: Monitoring data can help optimize the operation of the power system, improve energy utilization, and reduce energy consumption and costs.
Provide real-time monitoring data and reports: The power parameters are collected by sensors, the monitor processes the data and issues an alarm, and the data transmission device transmits the monitoring data to the host computer or cloud server. Managers can perform real-time monitoring and data analysis, provide data reports and decision support. -
3. Why do we need PMIC ?
PMIC (power management IC) plays a vital role in modern electronic devices. It can effectively manage and optimize the use of power to ensure the stable operation of the equipment and extend the battery life.
The core functions of PMIC include:
Power status monitoring: real-time monitoring of parameters such as battery power, voltage and current, judging the power status according to the set threshold, and issuing warning signals when necessary.
Energy optimization: Automatically adjust the power supply mode according to the equipment usage and requirements to meet the needs of the equipment and avoid energy waste.
Protection function: Provide overload, overheating, short circuit and other protection functions to ensure the safe operation of the equipment.
Energy saving function: Automatically reduce the power supply power or enter the energy saving mode when the equipment is in standby mode to extend the battery life.
The importance of PMIC is reflected in many aspects:
Improve equipment performance and responsiveness: By optimizing power transmission, ensure that components receive the right power at the right time, thereby improving equipment performance and responsiveness.
Extend battery life: Reduce power waste, extend battery life, and reduce environmental impact.
Miniaturize equipment: Play a role in high power density and integration to achieve miniaturization of electronic products.
Ensure equipment safety: Through a variety of protection functions, ensure that the equipment can operate safely under various working conditions.
In summary, PMIC is indispensable in modern electronic devices. It not only improves the performance and safety of the equipment, but also extends battery life and reduces environmental impact. It is a key technology for realizing efficient, safe and miniaturized electronic devices. -
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.
