The LTC4080EMSE#TRPBF battery charger is a part of the Polymer Multichemistry In-System Chargers (PMIC) family of products. It is designed to manage the charging of Lithium-Ion (Li-Ion) and Lithium-Ion Polymer (Li-poly) batteries. The part is available in a 10-Lead Micro Small Outline (MSOP) package and features a power-optimized architecture for charging batteries used in space-constrained portable applications. The charger is capable of charging batteries from a wall adapter or USB power source. It also has an LDO regulator, which allows for the regulation of the VDD voltage of the system when not charging.

The LTC4080EMSE#TRPBF application field revolves around portable products such as cameras, PDAs, mobile phones and wireless headsets. The tiny MSOP package is ideal for space-constrained applications. The 10-lead package also reduces the number of components replaced, which in turn increases production efficiency. Furthermore, the LTC4080EMSE#TRPBF is designed to provide high-quality power to the battery as well as additional system loads. This allows designers to reduce the number of power supply and battery charger components on the board.

The working principle of the LTC4080EMSE#TRPBF is based on a number of charge pumping stages. An internal 3.2-V voltage reference is used to ensure that charging remains within the safe operating zone of the battery. A charge current is monitored with an internal current sense amplifier and an internal analog-to-digital converter (ADC). A compensation network is also incorporated to optimize efficiency, power dissipation, and charging accuracy. The battery charging process is also monitored. This is done through a Charge Status Output (CSO) pin, which is used to indicate the status of the charging cycle. The processor within the part will automatically enter a recharge state if the battery voltage drops below a preset level.

The LTC4080EMSE#TRPBF offers a number of features and benefits for designers. It can be used in applications requiring dual inputs for charging the battery, or for providing system power. The charger contains a programmable soft start feature, which allows designers to reduce the charge inrush current. The part also contains a charging timer, which can be used to ensure that the battery has not been overcharged. This timer can be configured by the designer to accurately meet the requirements of the application.

The LTC4080EMSE#TRPBF is a highly integrated power management IC (PMIC). It has been designed to meet the requirements of space-constrained, portable applications. The part provides the ability to charge Lithium-Ion and Lithium-Ion Polymer batteries from a wall adapter or USB power source. Furthermore, the part offers an internal LDO regulator for powering the host system, and implements a number of safety features to protect the battery from overcharging and short circuit conditions. These features make the LTC4080EMSE#TRPBF an ideal solution for portable applications requiring safe and efficient charging of lithium-ion batteries.
