FEATURES

The RV5VG×××series Li-ion cell protectors are circuits designed for detecting overcharging and excessive dis-

charging of rechargeable single-cell lithium-ion batteries (based on the CMOS process). Besides detecting over-

charging 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.

Each of these protectors comprise two voltage detectors, a hysteresis circuit, a reference voltage source, a logic

circuit, a short-circuit protector and a charger connection detection-circuit. Of the two voltage detectors, VD1

detects overcharging (rising edge of waveform) while VD2 detects excessive discharging (falling edge of waveform).

Voltage output switches to a low (“L”) state if either a rising or falling voltage level is detected. When a short pro-

tection circuit is activated while D

OUT output is at “H” level, DOUT output switches to “L” level after internally set

delay time, which, in turn, switches to “H” level when short is cleared. Required current after detection of over-

discharge is suppressed to minimum by stopping the internal circuit.

Using an external capacitor, the output delay time of the voltage detector for excessive discharge/overcharge

can be set.

The series employ CMOS output type.

APPLICATIONS

•

Li-ion single cell protectors for power pack.

•

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

Absolute Maximum ratings are threshold limit values that must not be exceeded even for an instant under any

conditions. Moreover, such values for any two items must not be reached simultaneously. Operation above

these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress

ratings only and do not necessarily imply functional operation below these limits.
