SS6803
Three-cell Lithium-Ion Battery Protection IC
FEATURES
Ultra-low quiescent current of 13µA (Vcell = 3.5V). Ultra-low power-down current of 1.3µA (Vcell = 2.3V). Wide supply voltage range: 2V to 18V. Precision over-charge protection voltage: 4.35V±30mV for the SS6803A 4.30V±30mV for the SS6803B 4.25V±30mV for the SS6803C 4.20V±30mV for the SS6803D 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.
DESCRIPTION
The SS6803 is designed to protect a lithium-ion battery from damage or degraded lifetime due to over-charging, over-discharging and over-current for three-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.
APPLICATIONS
Protection IC for three-cell lithium-ion battery pack.
