Power Management Integrated Circuits (PMICs) are a class of integrated circuits that use power requirements to perform various power management functions. They are solid-state devices that regulate the flow and direction of electrical current. Many electrical devices use multiple internal voltages (e.g., 1.8V, 3.3V, 5V, etc.) and external power sources (e.g., battery and wall outlet), implying that the power design of the device has multiple operational requirements. They are primarily used in consumer electronics, automotive, telecommunications, and networking.
A PMIC can refer to any chip that performs a single power-related function, but it most commonly refers to integrated circuits (ICs) that perform multiple power conversions and power controls such as voltage supervision and undervoltage protection. By combining these functions into a single IC, the overall design can be improved in a variety of ways, including higher conversion efficiency, smaller solution size, and better heat dissipation.
There are basically two types of PMICs. They are:
1. Low-Power PMICs
Low-power PMICs offer high efficiency and compact form factors required for space-constrained applications like hearables, wearables, sensors, and IoT devices.
2. High-Power PMICs
For computationally intensive platforms such as systems-on-chip (SoCs), FPGAs, and application processors, high-power PMICs maximize performance per watt while increasing system efficiency.
A PMIC may have one or more of the following features:
1. Battery Charging
2. Battery Management
3. Voltage Scaling
4. Voltage Regulation
5. Frequency Scaling
6. DC to DC conversion
7. Power-source selection
8. Power sequencing
1. A PMIC is frequently used to reduce the amount of space required in battery-powered devices such as mobile phones and portable media players.
2. They are also commonly used to power small, battery-powered devices because the integration of multiple functions into a single chip results in more efficient use of space and system power.
3. Using a PMIC allows you to reduce the number of components and system size without sacrificing efficiency or thermal performance.
According to numerous customer reviews, TI is the best PMIC. TI has been at the forefront of developing new process, packaging, and circuit-design technologies for decades in order to deliver the best power devices for your design.
Scalable Power Management Integrated Circuits from TI leverage cutting-edge power technology to reduce system complexity with fewer components. When compared to a fully discrete solution, TI PMIC simplifies your design with built-in LDO regulators, DC/DC regulators, sequencers, load switches, supervisors, BISTs, and logic help.
As industrial and automotive processor power requirements evolve year after year, so does the demand for system adaptability and higher performance. TI PMICs offer a versatile and robust solution.
Below are some of the reasons why TI PMIC is the best PMIC you can use:
1. It boosts power density.
2. It increases battery life.
3. It decreases electromagnetic interference.
4. It maintains power and signal integrity.
5. It keeps you safe in the presence of high voltages.
Because they can perform multiple functions on a single chip, TI PMICs help to reduce the number of components required for the project, allowing you to eliminate the cluster of components on board.
Another feature that makes TI PMICs suitable for projects that are subjected to high temperatures and pressure is heat dissipation.
Because of the increasing processing power in various electronic devices, there is a greater need for careful power management. This has prompted major electronics manufacturers to develop sophisticated power management chipsets with specialized power management ICs designed for specific consumer requirements.
