description: |
  RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for
  portable applications. It integrates a synchronous PWM controller, power
  MOSFETs, input current sensing and regulation, high-accuracy voltage
  regulation, and charge termination. The charge current is regulated through
  integrated sensing resistors.

  The RT9467 also features USB On-The-Go (OTG) support. It also integrates
  D+/D- pin for USB host/charging port detection.
