R5460N208AA-TR-FE

Ricoh Elec Devices · Battery Management · SOT-23-6

R5460N208AA-TR-FE from Ricoh Elec Devices, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DOUT output Output pin of the over-discharge and excess discharge-current detectors, CMOS output, switching to L after a fixed internal delay when discharge voltage crosses the detector threshold.
2 COUT output Output pin of the over-charge detector, CMOS output, switching to L after a fixed internal delay when the over-charge threshold is crossed (returns to H on release).
3 V- power_in Charger negative input pin, used for excess charge-current and excess discharge-current detection; the code list gives an excess discharge-current threshold of 0.200 V and an excess charge-current threshold of -0.200 V for version R5460N208AA.
4 VC input Input pin for the center voltage between the two cells.
5 VDD power_in Power supply pin and substrate voltage level of the IC; operating input voltage (VDD-VSS) is 1.5 V to 10.0 V, absolute maximum -0.3 V to 12 V.
6 VSS power_in Ground pin for the IC.
