Overview

    TP4221X is a single-chip solution specially designed for mobile power supplies. It integrates charging management module, discharge management module, protection module, power detection and LED indication module.

    TP4221X has built-in charging and discharging power MOS. The charging current can be set. The maximum charging current is 1A and the maximum discharging current is 1.2A.

    TP4221X internally integrates almost all safety protection functions such as constant temperature charging mode, over-temperature protection, overcharge and over-discharge protection, output overvoltage protection, output overload protection, output short-circuit protection, etc. to ensure the safety of the chip and lithium-ion battery. TP4221X has a simple application circuit and only requires a few components to achieve charge management and discharge management.
