The working principle of the LTC4065LEDC#TRPBF is based on the charging algorithms developed by Linear Technology Corporation. It works in two stages: the precharge and the charge cycle. In the precharge stage, the input is connected to the battery to begin charging. A small amount of current is then applied to the battery and the voltage is monitored for the first few minutes to ensure that the battery is not over-discharged. Once the battery is above a predetermined voltage threshold, the charge cycle phase begins. This is when the steps to control the current and voltage applied to the battery occur, until the predetermined maximum voltage is reached and the charge cycle is completed. The frequency of the charge cycle is generated by an oscillator inside the device and can be adjusted with an external resistor.

In conclusion, the LTC4065LEDC#TRPBF is a low-power, 20V maximum, 1.6μA quiescent current battery charger ideal for use in power-sensitive applications. Its advanced features and charging algorithms make it an ideal choice for battery charging in extreme temperatures. It features three regulated current levels and a low quiescent current, as well as safety protection features to ensure a safe charge. It is in the PMIC - Battery Charger category and its working principle is based on the charging algorithms developed by Linear Technology Corporation.
