Product Specifications

The R5480 is a protection IC for over-charge of rechargeable Lithium-ion (Li+)/Lithium polymer battery. The R5480 can detect over-charge, over-discharge, excess-discharge current, and excess-charge current of onecell 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

Operating Input Voltage Range 1.5 V to 5.0 V (Absolute Maximum Rating: 30 V)
Supply Current Typ. 4.0 µA
Standby Current Max. 0.1 µA
Over-charge Detector Threshold Range 4.1 V to 4.5 V (0.005 V Step)
Voltage Accuracy ±20 mV
Output Delay Time 1.0 s
Over-discharge Detector Threshold Range 2.1 V to 3.0 V (0.005 V Step)
Voltage Accuracy ±35 mV
Output Delay Time 20 ms, 132 ms
Excess
discharge-current
Detector Threshold Range 0.030 V to 0.048 V (0.001 V Step)
Voltage Accuracy ±15%
Output Delay Time 12 ms
Excess
charge-current
Detector Threshold Range −0.030V to −0.020 V (0.001 V Step)
Voltage Accuracy ±15%
Output Delay Time 16 ms, 8 ms
Short Current Protection Output Delay Time 250 µs
Output Delay Time Shortening Function At COUT is “H”, if V- level is set at −2.0 V, the Output Delay time of detect the over-charge and over-discharge can be reduced (Delay Time for over-charge becomes about 1/100 of normal state).
