Describe
The RLCP5402 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 RLCP5402 integrates a 1A 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 RLCP5402 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 1A output current with efficiency up to 91%. At no load it automatically enters sleep
mode, reducing quiescent current to 9uA.
