A power management integrated circuit (PMIC) refers to a set of integrated circuits with the ability to perform various power management functions and power rails within a single miniature chip. Most electronic devices depend on batteries as their main power source and need distinct voltages to power their components. Power management ICs carry out all these functions without efficiently draining the batteries. The system-on-chip devices offer various functions, some of which include:
DC to DC switching devices are designed to generate output voltages below or above the input supply. These devices are integrated circuits that regulate voltages in high-efficiency circuits.
PMICs include battery management ICs that charge, measure, and monitor the device’s battery or battery packs. A battery management system provides data to ascertain the proper maintenance, function, or replacement of the battery and measures the battery’s health.
The devices also function to charge and replenish the batteries upon exhaustion by passing an electric current across them.
Various integrated circuits regulate the optimum voltage for multiple circuits. These devices regulate the system’s voltage during inactive voltage regulation to maintain the voltage at the given range.
Available Power Management (IC) and Their Functions
Enrgtech stocks various PMIC devices with various functions, such as:
- AC-DC Converters – Ideal for a wide range of electronic devices, these converters are used to convert alternating current (AC) to direct current (DC). They are primarily found in computer modems, routers, and other devices.
- DC-DC Converters – These devices transform a specific DC input voltage into a DC output voltage with the ability to increase and decrease the output voltage for their input voltages.
- DC-DC Controllers – These controllers serve to manage the battery’s charge.
- MOSFET power drivers – These include power drivers with the ability to function specifically with MOSFET semiconductor components.
- Buck Converters – They are also called Step-down converters, DC-to-DC converter types, designed to operate at a lower voltage than their relative input voltage.
- Voltage References – These high-performance voltage references supply stable voltages even in the event of heavy loads.
- Intelligent power switches – They actively respond to and monitor elevating electrical conditions in various circuits.
- Special Purpose Regulators- These are designed to offer specific functions and are
- distinguished for their particular applications.
- Linear voltage regulators – These devices maintain a constant voltage in electrical systems, allowing multiple loads to attach to various electrical systems while remaining stable.
- Motor driver ICs – These power drivers are used in large-scale industrial electric motors.
