The S-8215A Series is used for secondary protection of lithium-ion rechargeable batteries, and incorporates high-accuracy voltage detection circuits and delay circuits. Short-circuiting between cells makes it possible for serial connection of 3 cells to 5 cells.

Features

High-accuracy voltage detection circuit for each cell: Overcharge detection voltage n (n = 1 to 5)
3.60 V to 4.70 V (in 50 mV steps)
Accuracy ±25 mV (+25°C)
Accuracy ±30 mV (−5°C to +55°C); Overcharge hysteresis voltage n (n = 1 to 5)
0.0 mV to −550 mV (in 50 mV steps)
−300 mV to −550 mV Accuracy ±20%
−100 mV to −250 mV Accuracy ±50 mV
0.0 mV to−50 mV Accuracy ±25 mV
Delay times for overcharge detection can be set by an internal circuit only (external capacitors are unnecessary)
Output form is selectable: CMOS output, Nch open-drain output, Pch open-drain output
Output logic is selectable: Active “H”, Active “L”
High withstand voltage: Absolute maximum rating: 28 V
Wide operating voltage range: 3.6 V to 26 V
Wide operating temperature range: −40°C to +85°C
Low current consumption: At Vcun – 1.0 V for each cell: 3.0 µA max. (+25°C); At 2.3 V for each cell: 1.7 µA max. (+25°C)
Lead-free, Sn 100%, halogen-free (Refer to “Product Name Structure” for details.)

Applications

Lithium-ion rechargeable battery packs (for secondary protection)
