1 / 12 page  www.SiliconStandard.com 1 of 12 SS6804 Three/Four-cell Lithium-Ion Battery Protection IC FEATURES Ultra-low quiescent current, 17 µA (4-cell, Vcell = 3.5V). Ultra-low power-down current, 2.2 µA (4-cell, Vcell = 2.3V). Wide supply voltage range: 2V to 18V. Precision over-charge protection voltage: 4.35V ±30mV for the SS6804A 4.30V ±30mV for the SS6804B 4.25V ±30mV for the SS6804C 4.20V ±30mV for the SS6804D Externally set over-charge, over-discharge and over-current delay time. Built-in cell-balancing bleeding network under over-charge condition. Three detection levels for over-current protection. APPLICATIONS Protection IC for three/four-cell lithium-ion battery packs. DESCRIPTION The SS6804 is designed to protect a lithium-ion battery from damage or degraded lifetime due to over-charging, over-discharging and over-current for three- or four-cell lithium-ion battery powered systems such as notebook PCs. It provides the cell-balancing "bleeding" function to automatically discharge the over-charged cell until the over-charge condition is eliminated. Safe charging with full utilization is ensured by the accurate ±30mV over-charge detection. Four different specification values for over-charge protection voltage are provided for various protection requirements. The very low standby current represents little drain from the cell while in storage.
