Independent linear lithium battery charger with a thermistor input input.Small Human Body Sensor

　　This is a complete, flexible and independent linear single -section lithium -ion battery charger, which is in line with the USB power supply specification range. Can be used for programming time and programmable current based on terminate schemes. In addition, the programming function of the CHRG leakage state pins is an application that indicates the charging state of the battery as required. In order to maximize extension of battery life and reliability, other security functions are designed, including NTC battery temperature sensing and SmartStart charging algorithm.

　　Internal thermal feedback adjusts the charge current to keep the chip temperature constant high power run or high environmental temperature conditions. It does not require external detection resistance or external MOSFET architecture to be charged. The charging current can be used for external programming resistance. After power -on, the independent linear lithium -ion battery charger can be put in the turbine mode to reduce the current to 20µA, and the leakage current of the battery is less than 5µA.

　　Other functions include smart charging, USB C/5 current programming input, low -voltage locking and AC current logic output.

　　Features:

　　■ The charging current can be programmed to 1A

　　■ Directly lithium -ion battery, USB port directly from the charging elog

　　■ Preset charging voltage, accuracy of ± 0.35 %

　　■ Input and charge the thermistor that meets the temperature requirements

　　■ The input power supply exists logic output

　　■ Thermal regulation can maximize the charging ratio and reduce the risk of overheating overheating

　　■ Programmable charging current detection/termination

　　■ Programmable charging termination timer

　　■ Smart pulse error function

　　■ SmartStarttm extend battery life

　　■ The static current of the 20 状A charger in the disconnection state

　　■ Provide flat (0.75mm) 10 pins
