Onlinecomponents.com, an authorized distributor of Seiko Inst. Comp. Div. products, features the S-8261 series. The S-8261 series are lithium-ion / lithium polymer rechargeable battery protection ICs with built-in high-accuracy voltage detection circuit and delay circuit. The series are designed to be suitable for protection of single-cell Li-ion/Lithium polymer battery packs from overcharge, overdischarge, and overcurrent.
Features
- Internal high accuracy voltage detection circuit
- High voltage device is used for charger connection pins (VM and CO pins: absolute maximum rating = 28 V).
- Delay times (overcharge: tCU, overdischarge: tDL, overcurrent 1: tlOV1, overcurrent 2: tlOV2) are generated by an internal circuit. No external capacitor is necessary. Accuracy: ±20%
- Three-step overcurrent detection circuit is included (overcurrent 1, overcurrent 2 and load short-circuiting).
- 0 V battery charge function “Available” / “Unavailable” are selectable.
- Power-down function “Yes” / “No” are selectable.
- Charger detection function and abnormal charge current detection function
- Low current consumption
- Wide operating temperature range −40°C to +85°C
- Lead-free, Sn 100%, halogen-free
Applications
- Lithium-ion rechargeable battery packs
- Lithium polymer rechargeable battery packs
