S-8233AGFE-TB集成电路（IC）的电池管理规格书PDF中文资料

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.

(5) Three over current detection levels (protection for short-circuiting)

(6) Internal charge/discharge prohibition circuit via the control terminal

(7) The function for charging batteries from 0 V is available.

(8) Low current consumption

• Operation 50 µA max. (+25 °C)
