PMIC - Battery Management
Battery managers, Power management integrated circuits, abbreviated as (PMIC) are physical, electronic components that are used for the management of battery-related issues like monitoring, control tasks like authentication, cell balancing, condition monitoring, fuel measuring, source range, short circuit protection, over, and under-voltage protection, and others. However, some products of this group may have functionality for charging a battery. A PMIC can prove to be multi-functional such as:
Voltage Control
Results as passive voltage regulators for several device properties on the circuit. When the voltage of a system drops or rises, a particular action is carried out to regulate the given range of voltage.
Battery Management
Estimating, monitoring, and charging the battery or a battery built-in in a gadget. Additionally, battery management systems (BMS) are also responsible for measuring the battery’s health condition offering the data to ensure whether the battery is properly functional or if it needs to be changed.
Battery Charging Tasks
Enables the potential charge in batteries to be refilled when completely discharged. This is accomplished by operating an electrical current over the battery.
Importance of PMIC - Battery Management:
Battery management (PMIC) is important because they have a linear regulator like Low Dropout (LDO) and single or multiple switching DC-to-DC converters like buck or boost converters. The power transistor, a sizable transistor with an area of a few square millimeters configured as numerous banks of transistors, is the essential component of a PMIC. To reduce power loss and heat and maximize the efficiency of the power conversion, it is essential for these parallel devices to have very low resistance.
Types of PMIC- Battery Management:
PMIC- battery management is primarily of two types.
High - Performance PMICs
As its name suggests, this type of PMIC is designed to carry out high performance heavy tasks with numerous industrial applications.
Low-Power PMICs
Low-power PMICs are designed to perform delicate operations; these PMICs are used in houses, markets, and other small business areas.
Applications of PMIC - Battery Management:
The use of PMICs can be typically observed in the following applications.
- Manufacturing and engineering fields
- Automobiles
- Personal and Commercial electronic devices
- Alternative to Direct current
- Direct to Direct conversion
- Direct to Direct current Controllers
- Buck Converters
- Motor driver
- Voltage Source
- Linear Voltage regulator (LVR)
