BATTERY PROTECTION IC

FOR 3-SERIAL-CELL PACK

S-8233B Series

The S-8233B is a series of lithium-ion rechargeable battery protection ICs

incorporating high-accuracy (±25 mV) 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

3.80 ± 0.025 V to 4.40 ± 0.025 V

5 mV - step

• Over charge release voltage

3.45 ± 0.100 V to 4.40 ± 0.100 V

5 mV - step

(The over charge release voltage can be selected within the range where a difference from over

charge detection voltage is 0 to 0.35 V with 50 mV - step)

• Over discharge detection voltage

2.00 ± 0.08 V to 2.80 ± 0.08 V

50 mV - step

ΠOver discharge release voltage

2.00 ± 0.10 V to4.00 ± 0.10 V

50 mV - step

(The over discharge release voltage can be selected within the range where a difference from over

discharge detection voltage is 0 to 1.2 V with 50 mV - step)

• 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)

• Power-down

0.1 μA max. (+25°C)

(9) Lead-free products
