Overview
134n3p is a single-chip solution designed specifically for mobile power supplies, which integrates charging management module, discharge management module, battery detection and LED indicator module, as well as protection module 134N3P has built-in charging and discharging power MOS, and the charging current can be set. The maximum charging current and maximum discharging current are 1A The 134N3P integrates almost all safety protection functions such as constant temperature charging mode, over temperature protection, over charge 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 application circuit of the 134N3P is simple, and charging and discharging management can be achieved with very few components.
