The LT3652IDD#PBF is a highly integrated dual-input linear Li-ion/polymer battery recharge and power management IC. It is a member of the LTpowerCAD™ family of products and suitable for use in a variety of applications such as notebook computers, tablets, and ultrabooks. It features two integrated buck regulators to precisely and flexibly charge Li-ion/polymer batteries from a combination of input sources such as adapter, USB, and system supplies, along with a programmable output discharge path for powering the system and system peripherals.

LT3652IDD#PBF belongs to the PMIC (Power Management IC) - Battery Chargers, which are devices that are used to charge batteries. The LT3652IDD#PBF not only provides the ability to charge batteries but also provides power management, making it an ideal device for portable applications.

The LT3652IDD#PBF is designed to convert the input DC voltage to a regulated, controlled voltage and current which can be used to charge the battery. The device consists of multiple power conversion stages, each of which generates a slightly different type of output required for charging.

The key components of LT3652IDD#PBF include a boost pin for adapter voltage sources, USB input port for USB sources, a dedicated buck regulator for system supplies, and a discharge pin for system loads. The device also contains a dual-input topology (input voltage and system supply or adapter voltage and USB voltage) that provides individual input overvoltage protection, eliminating the need for an external overvoltage protection circuit. In addition to its primary functions, the device includes an onboard switch-mode power converter to facilitate power management such as power-on reset, low battery detection, and system reset.

In summary, the LT3652IDD#PBF offers a highly integrated dual-input linear Li-ion/polymer battery recharge and power management solution suitable for notebook computers, tablets, and ultrabooks. It provides a variety of features such as programmable output discharge path, dual-input topology, input overvoltage protection, and power management.
