BATTERY PROTECTION IC
FOR 4-SERIES OR 5-SERIES CELL PACK
Rev.1.5_01
The S-8205A/B Series includes high-accuracy voltage detection circuits and delay circuits, in single use, makes it possible
for users to monitor the status of 4-series or 5-series cell lithium-ion rechargeable battery.
The S-8205A/B Series is suitable for protecting lithium-ion rechargeable battery pack from overcharge, overdischarge, and
overcurrent.

• Settable by external capacitor; Overcharge detection delay time, Overdischarge detection delay time, Discharge
overcurrent detection delay time, Charge overcurrent detection delay time
(Load short circuit detection delay time is internally fixed.)
• S-8205A Series: used for 4-series cell, S-8205B Series: used for 5-series cell
• Independent charging and discharge control by the control pins
• Power-down function "yes" / "no" is selectable.
• High-withstand voltage element
Absolute maximum rating : 28 V
• Wide range of operation voltage
2 V to 24 V
• Wide range of operation temperature
Ta = −40°C to +85°C
• Low current consumption
During operation
40 μA max. (Ta = +25°C)
During power-down
• Lead-free (Sn 100%), halogen-free*5
0.1 μA max. (Ta = +25°C)
*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.
Application
• Rechargeable lithium-ion battery pack
Package
• 16-Pin TSSOP
