5V Step-up Board Lithium Battery Charging Protection Board

Overview:

134n3p is a single-chip solution designed specifically for mobile power supplies, which integrates a charging management module, discharge management module, battery detection and LED indicator module, as well as a protection module The 134N3P has built-in charging and discharging power MOS, and the charging current can be set. The charging current and discharging current are 1A The 134N3P is internally integrated with 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. At the same time, the 134N3P application circuit is simple, and charging management and discharge management can be realized with only a few components.
