Li-ion/polymer 2Cell protector
The R5460x 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 six 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 packages, DFN(PLP)1820-6 is also available.

|Variety of detector threshold||Over-charge|| 4.1V to 4.5V (0.005V steps)
3.5V to 4.0V (0.005V steps)
|Over-discharge||2.0V to 3.0V (0.1V steps)|
|Excess discharge-current||0.05V to 0.20V (0.005V steps)|
|Excess charge-current||-0.1V or -0.2V or -0.4V|
|Internal fixed Output delay time||Over-charge detector Output Delay||1.0s|
|Over-discharge detector Output Delay||Typ.128ms|
|Short Circuit detector Output Delay||Typ.300µs|
|Output Delay Time Shortening Function||At COUT is “H”, if V-level is set at –1.6V, 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.
