Lithium Battery Power Management IC

Describe

The RLCP5401 is a power-bank management IC integrating lithium-battery charging management, LED indication and a boost converter. With very few

external components it forms a powerful power-bank solution. The RLCP5401 integrates a 0.8A linear charging mode and supports charging 0V

batteries. It offers trickle/constant-current/constant-voltage charging modes with a constant voltage of 4.20V (typical). Built-in IC temperature and input-voltage intelligent adjustment of

the charging current. The RLCP5401 uses a PMOSFET architecture plus a reverse-charging prevention circuit, so no external sense resistor or

blocking diode is required. Its synchronous boost converter delivers 0.8A output current with efficiency up to 91%. At no load it automatically enters

sleep mode, reducing quiescent current to 9uA.
