Detailed components: 2 MOS DW01AÂ Seiko 8205A
- DW01A is a lithium battery protection circuit, in order to avoid lithium batteries due to overcharge, over discharge, current is too large lead to shorten the battery life or battery damage is designed. It has a high accuracy of voltage detection and time delay circuit.
- 8205A has the advantage of internal integration of two identical nmos tube for lithium battery protection circuit is very convenient.
