Battery Protection IC for 1-cell Pack (Secondary Protection) S-8206A Series

The S-8206A Series is used for secondary protection of lithium-ion / lithium polymer rechargeable batteries, and incorporates a high-accuracy voltage detection circuit and a delay circuit.


High-accuracy voltage detection circuit
Overcharge detection voltage 3.50V to 5.00V(5mV step) Accuracy ±20 mV
Overcharge release voltage 3.10V to 4.95V*1 Accuracy ±50 mV
Detection delay time is generated only by an internal circuit
(external capacitors are unnecessary). 
Output logic
Active “H”, active “L” 
Output form
CMOS output, Nch open-drain output
Wide operation temperature range
Ta = -40°C to +85°C
Low current consumption
During operation: 1.5 μA typ., 3.0 μA max. (Ta = +25°C) 
Lead-free (Sn 100%), halogen-free

*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage can be selected from a range of 0.05 V to 0.4 V in 50 mV step.)
