Power management integrated circuits (PMICs) are semiconductor devices that are used for managing power supplies, voltage regulation, and battery charging and protection. PMICs are a type of integrated circuit or IC that provides power management solutions for all types of motion, standby and system-level control applications. In order to properly manage the current and voltage in a system, PMICs are used to provide a range of functions such as current regulation, power sequencing, power monitoring and control, power on/off, voltage conversion and general-purpose counter/timers. The LTC3110IFE#TRPBF is a highly integrated PMIC with features designed to support the regulated charging of a single-cell lithium ion (Li-ion) or lithium polymer (LiPo) battery.

LTC3110IFE#TRPBF Application Field

The LTC3110IFE#TRPBF is designed for applications where a rapid charge and discharge is required, such as portable electronic devices, smart phones and tablet PCs. It is ideal for use in portable electronic applications that require a battery with a high energy density and fast charge times, such as cordless phones, digital cameras and portable media players. The LTC3110IFE#TRPBF is also suitable for automotive and industrial applications that require a battery with a long life cycle and robust performance.

The LTC3110IFE#TRPBF is a highly integrated PMIC offering a wide range of features and benefits. It is designed for high efficiency, low quiescent current, long battery run times and fast charge times. It is capable of delivering up to 2A of steady output current and has an adjustable charge current up to 3A. A low-loss P-Channel MOSFET allows the device to deliver fast charging and minimal energy loss. The LTC3110IFE#TRPBF also features an integrated reverse-blocking diode which prevents reverse current flow. Other features include an adjustable charge voltage, a soft-start/stop capability and an over temperature/over current monitoring and protection.

LTC3110IFE#TRPBF Working Principle

The LTC3110IFE#TRPBF operates in constant-voltage (CV) and constant-current (CC) modes. In CV mode, the LTC3110IFE#TRPBF controls the voltage on the battery by limiting the charging current. This prevents the battery from overcharging and helps prolong its life. In CC mode, the LTC3110IFE#TRPBF controls the current on the battery and limits it to the programmed current. This ensures that the battery is receiving the optimal amount of current for charging. The LTC3110IFE#TRPBF also features a selectable voltage or current limit mode, allowing the user to choose between a voltage or current-limited charge for their application.

The LTC3110IFE#TRPBF also features programmable protection features to help protect the battery from overcharging, undercharging and over discharging. The overcharge protection feature monitors the battery voltage and shuts off the circuit if the voltage exceeds a preset limit. The overdischarge protection feature is designed to limit the amount of current that the battery can discharge. The undercharge protection feature limits the current drawn from the battery if the voltage falls below a certain level. Additionally, the LTC3110IFE#TRPBF also features a timer to ensure that the charge cycle time is optimized.

The LTC3110IFE#TRPBF is an ideal choice for applications that require a fast charge and discharge time. With its adjustable charge and discharge voltage and current, the device is suitable for a wide range of Li-ion and LiPo battery applications. It is also an ideal solution for automotive and industrial applications that require a battery with a long life cycle and robust performance.
