NCP1852AFCCT1G

NCP1852AFCCT1G is a battery charger highly integrated system with a fixed-frequency Pulse Width Modulation (PWM) controller, low ON-resistance MOSFETs, an output adjustable(2.7V to 4.2V ) battery regulation, and other features. It operates for up to 5A and can support 4-cell Lithium ion, NiMH, and alkaline batteries . With its added Smart Charge™ feature, and its five levels Programmable Charge Current, it is ideal for applications, such as mobile phones, PDAs, digital cameras, video camcorders, and other portable devices that require 5A charging, low cost, and a wide range of features.

NCP1852AFCCT1G Application Field and Working Principle:

NCP1852AFCCT1G is the battery charger of choice for many portable products and comes with a range of interesting features that make it a perfect solution for many mobile devices. Its compact design, high-efficiency rating, and smart charging capabilities make it ideal for powering devices such as smartphones and tablets. Some of its most interesting features include its low quiescent current, low switch capacitance, adjustable battery regulation, and five levels programmable charge current.

The NCP1852AFCCT1G charger uses two stages of charging to charge the battery: bulk charging, and constant current/constant voltage (CCCVC) charging. During the bulk-charge phase, the charger pumps current directly into the battery, while the voltage of the battery remains low, and is generally limited to a maximum of 4.2V. During the CCCVC phase, the charger limits the battery current to ensure that the battery voltage remains stable, while the current slowly decreases to a trickle-charging rate. The NCP1852AFCCT1G charger also employs a number of safety features to protect both the battery and the battery charging circuitry, such as over-current protection, temperature monitoring, and voltage regulation.

In addition to its two-stage charging architecture, the NCP1852AFCCT1G also features a smart charging module, which allows for precise digital control over the charging parameters. This feature is particularly useful for keeping the battery in optimum condition over its lifetime, as it allows for the accuracy of the charge current and voltage to be adjusted for the specific battery being charged. This also helps to precisely optimize battery charge levels, incase the device is being charged from a variety of different sources.

Overall, the NCP1852AFCCT1G charger is a perfect solution for many portable products that require a high-efficiency, smart charging feature set. Its low quiescent current, adjustable battery regulation, and five-level programmable charge current capabilities make it an ideal choice for smartphones, tablets, and other portable devices needing a fast, low-cost charge solution.
