This document introduces the RV5VG1×××series lithium-ion cell protectors. These products have low supply current, high accuracy detector threshold, variety of detector threshold, built-in protection circuit, adjustable short protection voltage, adjustable sensing delay, and small package.
The RV5VG1 series consists of circuits designed to detect overcharging and excessive discharging of single-cell lithium-ion batteries. These devices utilize a CMOS process and include built-in short-circuit protection to prevent excessive current flow. The protectors feature two voltage detectors: one for rising edge detection (over-charge) and one for falling edge detection (excessive discharge).

The typical supply current is 2.3 µA.
Yes, using an external capacitor; a delay of 43ms is achieved with a 1000pF capacitor.
They are used as Li-ion single cell protectors for power packs, cellular phones, and camcorders.
