SS6821 - Single-cell Lithium-lon Battery Protection IC

General Description

The SS6821 battery protection IC is designed to protect a lithium-ion battery from damage or reduced lifetime due to over-charge, over-discharge, and/or over-current in single-cell lithium-ion battery powered systems, such as cellular phones.

Key Features

  • Reduction in board size with miniature SOT-23-5 package and few external components. Ultra-low quiescent current of 7µA (VCC=3.5V). Ultra-low power-down current of 0.6 µ A (VCC=2.2V). Precision over-charge protection voltage 4.35V ± 50mV for the SS6821A 4.30V ± 50mV for the SS6821B 4.25V ± 50mV for the SS6821C 4.20V ± 50mV for the SS6821D Built-in delay-time circuits for over-charge, overdischarge, and over-current protection. Load detection function during overcharge mode. Two detection levels.
