Power Management IC (PMIC) is a type of integrated circuit used to manage DC power sources in various electrical and electronic systems. PMICs are able to monitor, regulate, and control the current and voltage of the power source, including the battery in the system. PMICs allow tight control rules and the ability to reduce system size and cost. One of the types of PMICs is the Battery Management System (BMS) which monitors and regulates the charging, discharging, and protection of the battery. Among the BMS products is the LV5113T-TLM-E.

The Application Field Of LV5113T-TLM-E
