The S-8242B 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 overcurrent.
Features
(1) High-accuracy voltage detection for each cell
• Overcharge detection voltage n (n = 1, 2) 3.9 V to 4.5 V (50 mV steps) Accuracy ±25 mV
• Overcharge release voltage n (n = 1, 2) 3.8 V to 4.5 V*1 Accuracy ±50 mV
• Overdischarge detection voltage n (n = 1, 2) 2.0 V to 3.0 V (100 mV steps) Accuracy ±50 mV
• Overdischarge release voltage n (n = 1, 2) 2.0 V to 3.4 V*2 Accuracy ±100 mV
*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage n (n = 1, 2) can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV steps.)
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage n (n = 1, 2) can be selected as 0 V or from a range of 0.1 V to 0.7 V in 100 mV steps.)
(2) Two-level overcurrent detection (overcurrent 1, overcurrent 2)
• Overcurrent detection voltage 1 0.05 V, 0.08 V to 0.30 V (10 mV steps) Accuracy ±15 mV
• Overcurrent detection voltage 2 1.2 V (fixed) Accuracy ±300 mV
(3) Delay times (overcharge, overdischarge, overcurrent) are generated by an internal circuit (external capacitors are unnecessary).
(4) 0 V battery charge function available/unavailable are selectable.
(5) Charger detection function
• The overdischarge hysteresis is released by detecting negative voltage at the VM pin (−0.7 V typ.) (Charger detection function).
(6) High-withstanding-voltage devices Absolute maximum rating: 28 V
(7) Wide operating temperature range −40°C to +85 °C
(8) Low current consumption
Operation mode 10 µA max. (+25°C)
Power-down mode 0.1 µA max. (+25°C)
(9) Small package SNT-8A, 8-Pin TSSOP
(10) Lead-free products
Applications
• Lithium-ion rechargeable battery packs
• Lithium polymer rechargeable battery packs
