Package
8-Pin TSSOP
(Overcharge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.1 to 0.4 V in
50 mV steps.)
(Overdischarge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.2 to 0.7 V in
100 mV steps.)
High-accuracy voltage detection for each cell
• Overcharge detection voltage n (n = 1 to 3)
• Overcharge release voltage n (n = 1 to 3)
• Overdischarge detection voltage n (n = 1 to 3)
• Overdischarge release voltage n (n = 1 to 3)
Three-level overcurrent detection (Including load short circuiting detection)
• Overcurrent detection voltage 1
• Overcurrent detection voltage 2
• Overcurrent detection voltage 3
Delay times (Overcharge, Overdischarge, Overcurrent) are generated by an internal circuit. (External capacitors are
unnecessary).
Charge / discharge operation can be inhibited via the control pin.
0 V battery charge function available / unavailable are selectable.
