Description
The 8254AA is a battery management IC designed for 3-serial- or 4-serial-cell lithium-ion/lithium polymer rechargeable batteries. It includes a high-accuracy voltage detector and delay circuit. The SEL pin allows for switching between 3-serial or 4-serial cells.
Specifications and features
(1) High-accuracy voltage detection for each cell
- Overcharge detection voltage: 3.9 V to 4.4 V (50 mV step), Accuracy ±25 mV
- Overcharge release voltage: 3.8 V to 4.4 V, Accuracy ±50 mV
- Overdischarge detection voltage: 2.0 V to 3.0 V (100 mV step), Accuracy ±80 mV
- Overdischarge release voltage: 2.0 V to 3.4 V, Accuracy ±100 mV
(2) Three-level overcurrent protection
- Overcurrent detection voltage 1: 0.05 V to 0.30 V (50 mV step), Accuracy ±25 mV
- Overcurrent detection voltage 2: 0.5 V, Accuracy ±100 mV
- Overcurrent detection voltage 3: VVC1 - 1.2 V, Accuracy ±300 mV
(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) Switchable between a 3-serial cell and 4-serial cell using the SEL pin
(5) Charge/discharge operation can be controlled via the control pins.
(6) High-withstand voltage Absolute maximum rating: 26 V
(7) Wide operating voltage range: 2 V to 24 V
(8) Wide operating temperature range: -40°C to +85°C
(9) Low current consumption
- During operation: 30 μA max. (±25°C)
- During power-down: 0.1 μA max. (±25°C)
(10) Lead-free, Sn100%, halogen-free
Application Scenarios
- Lithium-ion rechargeable battery packs
