RICOH R5433V Series Li- ion polymer 3 4 5 Cell Protector

R5433V Series Li-ion/polymer 3/4/5Cell protector

The R5433V 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 ten voltage detectors, reference units, a delay circuit, an oscillator, a counter, and logic circuits. Disconnection between the battery and the protection board can be detected. SSOP-16 package is available.
