R5432V Series
Li-ion/polymer 3/4/5Cell Batteries protector
No. EK-263-111103 Li-ion / Li-polymer Multi-Cell protect IC
The R5432V Series are high voltage CMOS-based protection ICs for over-charge/discharge of rechargeable 3/4/5cell Li-ion/Lithium
polymer battery. Each of these ICs is composed of voltage detectors, reference units, a delay circuit, a short circuit protector, an
oscillator, a counter, and logic circuits. A more than 6 Cells battery is available by Cascade connecti on. Dis con necti on de tec tion and
cell-balance function, which can reduce cell-unbalance, are available. SSOP-24 package is available.
