R5405x Series

Li-ion/polymer 1Cell Protector

Flyer

R5405x Series are high input voltage CMOS-based protection ICs for over-charge/discharge of rechargeable one-cell Lithium-ion (Li-ion) / Lithium polymer excess load current, further include a short circuit protector for preventing large external short circuit current and excess charge/discharge-current.

Each of these ICs is composed of four voltage detectors, reference units, a delay circuit, a short circuit protector, an oscillator, a counter, and a logic circuit.

In addition to SOT-23-6 package, DFN(PLP)1616-6 is also available.

Internal fixed Output delay time	Over-charge detector Output Delay	Typ.1.0s
	Over-discharge detector Output Delay	Typ.20ms
	Excess discharge-current	Typ.6ms or 12ms or 18ms
	Excess charge-current	Typ.8ms or 16ms
	Short Circuit detector Output Delay	Typ.200μs or 300μs or 400μs
Output Delay Time Shortening Function	At COUT is “H”, if V-level is set at –2.0V, the Output Delay time of detector and release the over-charge and over-discharge can be reduced. Delay time for over-charge becomes about 1/60 of normal state.
0V-charge option	Selectable
