BATTERY PROTECTION IC FOR 3-SERIAL OR 4-SERIAL CELL PACK
The S-8243A/B Series is a protection IC for lithium-ion rechargeable battery. The S-8243A Series protects 3-series, the S-8243B Series protects 4-series cell pack from the overcharge, overdischarge, overcurrent voltages. This IC has a high-accuracy battery protection circuit and a battery monitor amplifier, and also a voltage regulator which operates the microcomputer or gas gauge IC. Combining this IC and a microcomputer or a gas gauge IC allows to display the amount of charge remained in a battery.
Features
(1) High-accuracy voltage detection for each cell
• Overcharge detection voltage n (n = 1 to 4)
3.9 V to 4.4 V (50 mV step) Accuracy ±25 mV
• Overcharge hysteresis voltage n (n = 1 to 4) of overcharge detection
−0.10 V to −0.40 V (50 mV step) or 0 V Accuracy ±50 mV
(Overcharge release voltage n (= Overcharge detection voltage n + Overcharge hysteresis voltage n) can be
selected within the range 3.8 V to 4.4 V.)
• Overdischarge detection voltage n (n = 1 to 4)
2.0 V to 3.0 V (100 mV step) Accuracy ±80 mV
• Overdischarge hysteresis voltage n (n = 1 to 4) of overdischarge detection
0.15 V to 0.70 V or 0 V (50 mV step) Accuracy ±100 mV
(Overdischarge release voltage n (= Overdischarge detection voltage n + Overdischarge hysteresis voltage n)
can be selected within the range 2.0 V to 3.4 V.)
(2) Three-level overcurrent protection including protection for short-circuiting
• Overcurrent detection voltage 1 0.05 V to 0.3 V (50 mV step) Accuracy ±25 mV
• Overcurrent detection voltage 2 0.5 V Accuracy ±100 mV
• Overcurrent detection voltage 3 VDD / 2 Accuracy ±15
(3) Delay times for overcharge detection, overdischarge detection and overcurrent detection 1 can be set by external
capacitors. (Delay times for overcurrent detection 2 and 3 are fixed internally.)
(4) Charge/discharge operation can be controlled through the control pins.
(5) High-accuracy battery monitor amp GAMP = VBATTERY × 0.2 ±1.0
(6) Voltage regulator VOUT = 3.3 V ±2.4 (3 mA max.)
(7) High-withstand voltage Absolute maximum rating: 26 V
(8) Wide operating voltage range 6 V to 18 V
(9) Wide operating temperature range: −40°C to +85°C
(10) Low current consumption
• Operation mode 120 μA max.
• Power down mode 0.1 μA max.
(11) Lead-free, Sn 100, halogen-free*1
Applications
• Lithium-ion rechargeable battery packs
• Lithium polymer rechargeable battery packs
