onsemi NCP802
The NCP802 resides in a lithium battery pack where the battery cell continuously powers it. This circuit senses cell voltage, charge current, and discharge current, and correspondingly controls the state of two, N−channel MOSFET switches. These switches reside in series with the negative terminal of the cell and the negative terminal of the battery pack.- Min Voltage : 1.5V
- Max Voltage : 5V
- Channels : 1
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
