Power Management ICs

Battery Protection IC for 4-Series or 5-Series Cell Pack S-8205A/B Series

The S-8205A/B Series includes a voltage detection circuit with high accuracy and a delay circuit, in single use, makes it possible for users to monitor the status of 4-series or 5-series cell lithium-ion rechargeable battery. These ICs are suitable for protecting rechargeable lithium-ion battery packs from overcharge, overdischarge, and overcurrent.

*1. The overcharge detection voltage n (n = 1 to 5) and overdischarge detection voltage (n = 1 to 5) are not selectable if the voltage difference between them is 0.6 V or less.
*2. Overcharge hysteresis voltage n (n = 1 to 5) is selectable in 0 V, or in 0.1 V to 0.4 V in 50 mV step. (Overcharge hysteresis voltage = Overcharge detection voltage – Overcharge release voltage)
*3. Overdischarge hysteresis voltage n (n = 1 to 5) is selectable in 0 V, or in 0.2 V to 0.7 V in 100 mV step. (Overdischarge hysteresis voltage = Overdischarge release voltage – Overdischarge detection voltage)
*4. The discharge overcurrent detection voltage and load short circuit detection voltage are not selectable if the voltage difference between them is 0.3 V or less.
*5. Refer to “Product Name Structure” for details.
