The LTC4063EDD#TRPBF are Linear Technology’s family of linear battery chargers, optimized for microprocessor-based systems. The LTC4063EDD#TRPBF are intended to interface with internal or external power sources, while charging and providing power to single-cell Lithium Ion, Lithium Polymer and 3.6V LiFePO4 batteries. The part is comprised of both a DC/DC converter and Charge-Termination.

The LTC4063EDD#TRPBF is designed for systems that need to maintain multiple source power supplies and hold a charge for an extended time. This family of parts features an adjustable input current limit of 0.3mA to 2100mA. The device\'s shutdown current is typically 1µA so battery life is maximized. It also features integrated thermal loop regulation to reduce the risk of thermal runaway and minimize electrolyte evaporation during charge cycles.

The LTC4063EDD#TRPBF incorporates Charge Termination, allowing the charge cycle to be stopped at termination voltage without exceeding the maximum voltage. This design works best with single-cell lithium ion batteries. The LTC4063EDD#TRPBF also includes a reverse blocking MOSFET switch, allowing the user to control the power path direction, so that when the input voltage is greater than the battery voltage, power can be routed to other on-board devices.

The LTC4063EDD#TRPBF offers system reliability by monitoring input supply and battery voltages, as well as fault and thermal conditions. Additionally, the device includes several safety features such as input under-voltage and over-voltage protection, over-voltage protection, reverse current protection, soft-start and over-temperature protection.

The LTC4063EDD#TRPBF is a highly integrated and compact solution for applications that require a continuous power source in order to power a system. The flexibility of the part allows it to be used in a variety of consumer, industrial and automotive products. The device is also optimized for low noise and is compatible with consumer grade and automotive safety standards, making it an excellent choice for applications that require reliability, high performance and energy efficiency.

The working principle of the LTC4063EDD#TRPBF is based on its ability to operate as a high efficiency DC/DC converter. The device is capable of delivering up to 2100mA when supplied with a voltage between 1.8V to 5.5V. In order to maximize battery life and minimize ripple, the LTC4063EDD#TRPBF employs a constant frequency, PWM current mode controller.

To ensure the battery is charged appropriately and to prevent over-charging, the LTC4063EDD#TRPBF includes a Charge Termination feature. This feature is able to stop the charge cycle when the battery reaches a predefined charge termination voltage of 4.2V or 4.35V. The parts are also designed to prevent short-circuits and can detect when the battery is in a no-load state for automatic maintenance charging.

In summary, the LTC4063EDD #TRPBF from Linear Technology is a high efficiency, low-noise and high-performance battery charger designed for single-cell Lithium Ion, Lithium Polymer and 3.6V LiFePO4 batteries. The device is ideal for applications that require a constant power source in order to ensure battery life and reliability. It is capable of delivering up to 2100mA of current while including safety features to prevent over-charging and other faults.
