1 / 44 page S-82A1A Series www.sii-ic.com BATTERY PROTECTION IC FOR 1-CELL PACK © SII Semiconductor Corporation, 2016-2017 Rev.2.0_01 1 The S-82A1A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy voltage detection circuits and delay circuits. It is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. By using an external overcurrent detection resistor, the S-82A1A Series realizes high-accuracy overcurrent protection with less effect from temperature change. Features • High-accuracy voltage detection circuit Overcharge detection voltage 3.5 V to 4.6 V (5 mV step) Accuracy ±20 mV Overcharge release voltage 3.1 V to 4.6 V *1 Accuracy ±50 mV Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step) Accuracy ±50 mV Overdischarge release voltage 2.0 V to 3.4 V *2 Accuracy ±100 mV Discharge overcurrent detection voltage 1 0.010 V to 0.100 V (1 mV step) Accuracy ±3 mV Discharge overcurrent detection voltage 2 0.030 V to 0.200 V (1 mV step) Accuracy ±5 mV Load short-circuiting detection voltage 0.050 V to 0.500 V (5 mV step) Accuracy ±20 mV Charge overcurrent detection voltage −0.100 V to −0.010 V (1 mV step) Accuracy ±3 mV • Detection delay times are generated only by an internal circuit (external capacitors are unnecessary). • 0 V battery charge function is selectable: Available, unavailable • Power-down function is selectable: Available, unavailable • Release condition of discharge overcurrent status is selectable: Load disconnection, charger connection • Release voltage of discharge overcurrent status is selectable: Discharge overcurrent detection voltage 1 (VDIOV1), Discharge overcurrent release voltage (VRIOV) = VDD × 0.8 (typ.) • High-withstand voltage: VM pin and CO pin: Absolute maximum rating 28 V • Wide operation temperature range: Ta = −40°C to +85°C • Low current consumption During operation: 2.0 μA typ., 4.0 μA max. (Ta = +25°C) During power-down: 50 nA max. (Ta = +25°C) During overdischarge: 500 nA max. (Ta = +25°C) • Lead-free, Sn 100%, halogen-free P *3 *1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV step.) *2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage (Overdischarge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mV step.) *3. Refer to " Product Name Structure" for details. Applications • Lithium-ion rechargeable battery pack • Lithium polymer rechargeable battery pack Packages • SNT-6A • DFN-6(1414)A |
