Package Name

Internal high-accuracy voltage detection circuit

High input-voltage device (absolute maximum rating: 26 V)

Wide operating voltage range:

The delay time for every detection can be set via an external capacitor.

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

Internal charge/discharge prohibition circuit via the control terminal

The function for charging batteries from 0 V is available.

Operation

Power-down

(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)

(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)

50 µA max. (+25°C)

0.1 µA max. (+25°C)

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.
