Lithium battery fast charger composed of LM3420
Source: InternetPublisher:念念Brown Keywords: Quick charger lithium battery Updated: 2020/07/27
This circuit uses the LM 3420-8.4 special lithium battery charger. The circuit is simple and has excellent performance. It can quickly charge two lithium batteries. When the charging voltage reaches the rated value (4.2V for a single lithium battery), the charging current drops to trickle charging to prevent permanent damage to the lithium battery caused by overvoltage charging.
