IC LI-ION BATT PROTECT 16-TSSOP
The S-8233A Series is a series of lithium-ion rechargeable battery protection ICs incorporating high-accuracy voltage detection circuits and delay circuits. It is suitable for a 3-serial-cell lithium-ion battery pack.
■ Features
1 Internal high-accuracy voltage detection circuit
• Over charge detection voltage 4.10 ± 0.05 V to 4.35 ± 0.05 V 50 mV- step
• Over charge release voltage 3.85 ± 0.10 V to 4.35 ± 0.10 V 50 mV- step
The over charge release voltage can be selected within the range where a difference from over charge detection voltage is 0 V to 0.3 V
• Over discharge detection voltage 2.00 ± 0.08 V to 2.70± 0.08 V 100 mV- step
• Over discharge release voltage 2.00 ± 0.10 V to 3.70± 0.10 V 100 mV - step
The over discharge release voltage can be selected within the range where a difference from over discharge detection voltage is 0 V to 1.0 V
• Over current detection voltage 1 0.15 ±0.015 V to 0.5 ±0.05 V 50 mV-step
2 High input-voltage device absolute maximum rating: 26 V
3 Wide operating voltage range: 2 V to 24 V
4 The delay time for every detection can be set via an external capacitor.
