R5642L Series 1 to 3 Cells Li-Ion Battery Protection IC for Secondary Protection
■The R5642L is an overcharge protection IC for 1 to 3 serial cells Li-ion / Li-polymer rechargeable battery. This IC provides the high-accuracy voltage detection function and the shutdown function can reduce the supply current to the minimum when all cell's voltage becomes less than the shutdown detection voltage.
●KEY BENEFITS
■Low consumption current and low shutdown current: achieving longer driving time with a battery of small capacity
●KEY SPECIFICATIONS
■High Voltage Tolerant Process
▲Absolute maximum rating: 26 V
■Low Supply Current
▲Normal mode: Typ. 0.85 µA (VCELLn (1) : 3.9 V, for 3-cell)
■Overcharge Voltage Detector with High Accuracy
▲Detection voltage (VDET1n) and accuracy: 4.10 V to 4.65 V, ± 0.015 V (Ta = 25°C)
▲Release voltage (VREL1n): VDET1n – 0 V to VDET1n − 0.5 V
▲Delay time selectable (tVDET1): 2, 4, 6 sec, with delay shortening function (2)
▲Release condition: Auto release
■COUT Output (CMOS Output, Active-high): Typ. 4.7 V
■Shutdown Function
▲Detection voltage: Typ. 3.5 V ±0.3 V
▲Shutdown current: Max.0.1µA
■1 to 3 Cells Selectable Battery Protection
