OUTLINE

The RV5VG×××series Li-ion cell protectors are circuits designed for detecting overcharging and excessive discharging of rechargeable single-cell lithium-ion batteries (based on the CMOS process). Besides detecting overcharging or excessive discharging of single cell Li-ion battery, the RV5VG1×××series Li-ion cell protectors include a short-circuit protector to prevent excessive current due to an external short-circuit.

FEATURES

• Low Supply Current ................................................TYP. 2.3µA (for normal operations)

• High Accuracy Detector Threshold..........................over-charge ±50mV

over-discharge ±2.5

• Variety of Detector Threshold..................................over-charge 4.0 to 4.5 V(0.05V step)

over-discharge 2.0 to 3.0V(0.05V step)

• Built-in Protection Circuit

• Short protection voltage may be set insteps 0.05V within the range of 0.1V to 0.4V (accuracy±15)

• Adustable sensing delay for overcharging ......delay of 43ms when external 1000pF is installed

(VDD=4.3V)

• Adjustable sensing delay for excessive discharging.....delay of 24ms when external 1000pF is installed

(VDD=2.4V)

• Output Type .................................................................CMOS

• Small Package .............................................................8pin SSOP

APPLICATIONS

• Li-ion single cell protectors for power pack.

• High precision protectors for cellular phones, camcorders and any other gadgets using Li-ion cell.
