R5460x2xx SERIES
Li-ION/POLYMER 2-CELL PROTECTOR
NO.
EA-165-160603
OUTLINE
The R5460x2xxxx Series are high
voltage CMOS-based protection ICs for over-charge/discharge of rechargeable two-cell Lithium-ion (Li+) / Lithium polymer, further include a short circuit protection circuit for preventing large external short circuit current and the protection circuits against the excess discharge-current and excess charge current.
Each of these ICs is composed of six
voltage detectors, a reference unit, a delay circuit, a short circuit protector, an oscillator, a counter, and a logic circuit.
When the over-charge
voltage threshold or excess-charge current threshold crosses the each detector threshold...
