How DW01A works?
The DW01A requires an external dual FET to control the ground line to the battery. By using the FET, the ground line is disconnected during current error conditions (Short circuit, over discharge, over charge). This isolates the Lithium battery until the load is removed (in the case of a short circuit).
What is DW01A?
DW01A. The DW01A battery protection IC is designed to. protect lithium-ion/polymer battery from damage or. degrading the lifetime due to overcharge, overdischarge, and/or overcurrent for one-cell.
How do I keep my battery from over discharging?
A battery protection circuit should be used to prevent this. Lithium batteries are completely empty when discharged to 2.5 V/cell. Discharging a lithium cell this low is stressful to the cell and reduces cell lifetime. A good battery protection circuit will also provide over-discharge protection.
How does the dw01a battery protect the microcontroller?
The DW01A also has extended voltage limits (above and below normal voltage charging values) to protect from overcharging and overdischarging. It also has low standby current 3uA when inactive, so it does not drain the battery significantly during storage.
What is the dw01a chip on a lithium ion battery?
The DW01A chip is a battery protection device for a single cell Lithium Ion battery and it protects the cell from over and under charging, reverse connection and short circuit. You can typically find this chip on TP4056 breakout boards (Lithium ion charger chip).
What kind of Fet does the dw01a need?
The DW01A requires an external dual FET to control the ground line to the battery. By using the FET, the ground line is disconnected during current error conditions (Short circuit, over discharge, over charge).
Can a dw01a be used on a tp4056 board?
It has reduced functionality when used on the TP4056 board. The DW01A requires an external dual FET to control the ground line to the battery. By using the FET, the ground line is disconnected during current error conditions (Short circuit, over discharge, over charge).
