Source: InternetPublisher:偷熊计划 Keywords: Lithium battery charger BSP Updated: 2021/05/13
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.
