  13 description: |
  14   RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger for
  15   portable applications. It integrates a synchronous PWM controller, power
  16   MOSFETs, input current sensing and regulation, high-accuracy voltage
  17   regulation, and charge termination. The charge current is regulated through
  18   integrated sensing resistors.
  19
  20   The RT9467 also features USB On-The-Go (OTG) support. It also integrates
  21   D+/D- pin for USB host/charging port detection.
