Power management integrated circuits, also referred to as PMICs, are widely used in various industrial applications today. PMICs are responsible for managing power between the system’s supply and output and regulating the current. PMICs vary widely in their forms and functions and are often deployed depending on the type of system or application being powered.

Among the various types of PMICs, Battery Management PMICs (BQ) are one of the most widely used options, particularly for battery-operated systems. BQ PMICs are equipped with built-in batteries management algorithms and power electronics which enable the safe and efficient functioning of the batteries. These PMICs are mainly responsible for maintaining the health and performance of lithium-based batteries.

One such Battery Management PMIC is the BQ2018SN-E1TR. This is a highly reliable, low-cost system power management IC enabling secure communications, safe and efficient energy storage, and an optimized battery charge cycle.
