The S-8249 Series is a voltage monitoring IC with a cell balancing function and includes a high-accuracy voltage detection circuit and a delay circuit. The S-8249 Series is suitable for cell balancing and overcharge protection of batteries and capacitors.
Features
High-accuracy voltage detection circuit
Cell balancing detection voltage: 2.0 V to 4.6 V (5 mV step) Accuracy ±12 mV (2.0 V≦Vbu＜2.4 V), Accuracy ±0.5% (2.4 V≦Vbu≦4.6 V)
Overcharge detection voltage: 2.0 V to 4.6 V (5 mV step) Accuracy ±12 mV (2.0 V≦Vcu＜2.4 V) , Accuracy ±0.5% (2.4 V≦Vcu≦4.6 V)
Overcharge release voltage: 2.0 V to 4.6 V*2 Accuracy ±24 mV (2.0 V≦Vcl＜2.4 V) , Accuracy ±1.0% (2.4 V≦Vcl≦4.6 V)
Built-in Nch transistor with ON resistance of 5 Ω typ. between the CB pin and the VSS pin
Current consumption
2.0 μA max. (Ta = +25°C)
Delay times are generated only by an internal circuit (External capacitors are unnecessary).
CO pin output form and output logic are selectable
CMOS output Active “H”, active “L”
Nch open-drain output Active “H”, active “L”
Switchable to power-saving mode by using the CE pin
Operation temperature range
Ta = −40°C to +85°C
Lead-free (Sn 100%), halogen-free
*1. Cell balancing release voltage = Cell balancing detection voltage − Cell balancing hysteresis voltage (Cell balancing hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 50 mV step.)
*2. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 V to 0.7 V in 50 mV step.)
