R5480K Series 1-Cell Li-Ion Battery Protection IC NO.EA-308-201211 OUTLINE The R5480x is a protection IC for over-charge of rechargeable Lithium-ion (Li+)/Lithium polymer battery. The R5480x can detect over-charge, over-discharge, excess-discharge current, and excess-charge current of one- cell Lithium-ion (Li+)/Lithium polymer battery. The external resistor of RSENSE pin allows a high-accuracy detection for excess current. The supply current after detecting over-discharge is suppressed as much as possible by stopping the internal circuit. FEATURES High Voltage Tolerant Process Absolute Maximum Ratings 30 V Low supply current Supply current (At normal mode) Typ. 4.0 A Standby current Max. 0.1 A High accuracy detector threshold Over-charge detector 20 mV ( 4.5 V) / 25 mV (> 4.5 V) Over-discharge detector 35 mV Excess discharge-current detector 15% ( 30 mV) / 4.5 mV (< 30 mV) Excess charge-current detector 15% Variety of detector threshold Over-charge detector threshold 4.1 V to 4.7 V in step of 0.005 V Over-discharge detector threshold 2.1 V to 3.0 V in step of 0.050 V Excess discharge-current threshold 0.020 V to 0.050 V in step of 0.001 V Excess charge-current threshold 0.057 V to 0.020 V in step of 0.001 V Internal fixed Output delay time Over-charge detector Output Delay 1.0 s Over-discharge detector Output Delay 20 ms / 132 ms Excess discharge-current detector Output Delay 12 ms Excess charge-current detector Output Delay 16 ms / 8 ms Short Circuit detector Output Delay 250 s Output Delay Time Shortening Function When the V- level is set at 2.0 V (typ.) during the COUT pin of High, the output delay time for the over- charge and the over-discharge detections can be reduced (Delay time for over-charge becomes about 1/100 that of the normal state).
