Overview
134N3P is a single -chip solution designed for mobile supply. Internal integration of charging management modules, discharge management modules, power detection and LED indicator modules, and protection modules. 134N3P built -in charging and discharge power MOS. The charging current can be set.The maximum charging current and maximum discharge current 1A. 134N3P Internal integration of almost all safety protection functions such as the constant temperature charging work mode, over -temperature protection, overcharge and overload protection, output overload protection, output short -circuit protection, output short circuit protection, etc.The safety of chips and lithium ion batteries, at the same time, 134N3P application circuits are simple, and charging management and discharge management can be achieved with few components.
