Please contact each Web shop for details such as availability of online samples.

The S-8215C Series is used for secondary protection of lithium-ion rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. 
Short-circuiting between cells makes it possible for serial connection of three cells to five cells.

Features

High-accuracy voltage detection circuit for each cell
Overcharge detection voltage n (n = 1 to 5): 2.700 V to 4.700 V (5 mV step)
Accuracy ±20 mV (Ta = +25°C)
Accuracy ±25 mV (Ta = -10°C to +60°C)
Overcharge release voltage n (n = 1 to 5)*1: 2.700 V to 4.700 V
Accuracy ±50 mV (Ta = +25°C)
Overcharge detection delay times are generated only by an internal circuit (external capacitors are unnecessary)
Overcharge detection delay time: 0.5 s, 1 s, 2 s, 4 s, 6 s, 8 s
Output form
CMOS output, Nch open-drain output
Output logic
Active “H”, active “L”
Built-in test mode function to check overcharge detection voltage with shortened delay time
High-withstand voltage
Absolute maximum rating 28 V
Wide operation voltage range
3.6 V to 26 V
Wide operation temperature range
Ta = -40°C to +85°C
Low current consumption
During operation: 0.3 µA typ., 0.7 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 mV to −400 mV in 50 mV step.)

Applications
