R5400N Series

Li-ion/polymer 1Cell Protector

Flyer

The R5400N 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 discharge-current.

Each of these ICs is composed of three voltage detectors, reference units, a delay circuit, a short circuit detector, an oscillator, a counter, and a logic circuit. SOT-23-5 package is available.

Manufactured with High Voltage Tolerant Absolute Maximum Rating Process	Supply Voltage (VDD)	12V (Absolute Maximum Rating)
	Charge Negative Input voltage (V-)	-35V (Absolute Maximum Rating)
Low supply current	Supply Current (IDD)	Typ.3.5µA (A Version) Typ.4.0µA (B Version)
Low supply current	Standby Current (Is)	Max.0.1µA
High accuracy detector threshold	Over-charge	±25mV (25°C), ±30mV (-5 to 55°C)
	Over-discharge	±2.5%
	Excess discharge-current	±15mV
Variety of detector threshold	Over-charge	4.0V to 4.5V (0.005V steps)
	Over-discharge	2.0V to 3.0V (0.1V steps)
	Excess discharge-current	0.05V to 0.20V (0.005V steps)
Internal fixed Output delay time	Over-charge detector Output Delay	Typ.1.1s or 275ms
	Over-discharge detector Output Delay	Typ.20ms
	Excess discharge-current	Typ.12ms
	Short Circuit detector Output Delay	Typ.300µs
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
Package	SOT-23-5
