FS3332C-G
General Description
The FS3332 Series are protection ICs for 2-serial-cell lithium-ion/lithium-polymer rechargeable batteries and include high-accuracy voltage detectors and delay circuits.
These ICs are suitable for protecting 2-cell rechargeable lithium-ion/lithium-polymer battery packs from overcharge, overdischarge, and over-current.
Feature
| • | Low supply current Normal Operation : 7.5μA typ. 14.2μA max. Power-down mode : 0.3μA typ. |
| • | Overcharge detection voltage [VOCU] 3.90V~4.60V, Accuracy of ±25mV |
| • | Overcharge release voltage [VOCR] 3.60V~4.60V, Accuracy of ±50mV |
