OUTLINE
The R5475N/R5478Nxxxxx Series are high
voltage CMOS-based protection ICs for over-charge/discharge of rechargeable one-cell Lithium-ion (Li+) / Lithium polymer excess load current, further include a short circuit protector for preventing large external short circuit current and Excess discharge-current.
Each of these ICs is composed of three
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 crosses the detector threshold from a low value to a high value, the output of COUT pin switches to low level after in...
