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.
