PMIC - Battery ChargersThe LTC4054LES5-4.2#TRMPBF is a high-performance Lithium-ion battery charger with a range of features designed to make charging easier, faster, and more efficient. It is designed to charge single-cell Li-ion batteries with a maximum battery voltage of 4.2 V, and it has a 400mA constant current/constant voltage (CC/CV) charging algorithm. The charger also includes a precision 10 mA minimum current termination to help prevent overcharge, and a battery-detection circuit to monitor the battery’s state-of-charge (SOC).The LTC4054LES5-4.2#TRMPBF is suitable for a wide range of commercial and industrial applications, including the automotive industry, medical aid and measurement equipment, unmanned aerial vehicles (UAVs), and personal electronics such as tablets and mobile phones. It can also be used in electric vehicles (EVs), or in any up-and-coming application that requires a Lithium-ion battery-driven system.The type of battery being charged and the charging requirements for a particular application determine the charger’s configuration, which includes its operating parameters. For instance, if the battery being charged is a single-cell Li-ion battery with a maximum voltage of 4.2 V, the type of configuration used will be Constant-Current/Constant-Voltage (CC/CV), which is the most common type of charging configuratiohttps://en.wikipedia.org/wiki/Battery_chargern. This type of charging is designed to regulate both the voltage and current used to charge a battery, so that the battery does not become overcharged. The charger also includes a charge current timer, which turns off the charger after a predefined period.The charger features a built-in maximum current limit (ICL) and temperature limit (TTL) that help protect the battery from damage caused by overcharging or extreme temperatures. This helps ensure that the battery remains safe when charging. It also has a 10 mA minimum current termination, which helps prevent overcharge and prolongs battery life.The LTC4054LES5-4.2#TRMPBF also includes a battery-detection circuit (BLD), which can be used to monitor the battery’s state-of-charge (SOC). This feature allows the user to better manage the charging process and to maintain the battery’s optimum performance. The charger also has an Input Overvoltage Protection (IOV) feature, which protects the charger from being damaged by voltage surges.The LTC4054LES5-4.2#TRMPBF is a versatile, high-performance lithium-ion battery charger, suitable for a wide range of commercial and industrial applications. The charger provides a number of features to ensure efficient and safe charging, and its battery detection circuit can be used to monitor the battery’s state-of-charge (SOC). Its Input Overvoltage Protection (IOV) and maximum current limit (ICL) also ensure that the battery remains safe when charging.
