Introduction

AI Translation

RH7901/RH7902 are USB charging protocol port controller ICs that automatically identify the type of charging device and perform handshaking via the corresponding USB charging protocol, enabling the device to draw maximum charging current while protecting the charging device and minimizing charging time.

Features

AI Translation
  • Operating voltage: 4.5V ~ 5.5V
  • Dual-port control (RH7902): supports two independent USB charging protocol detection simultaneously
  • Supports multiple USB charging protocols with automatic switching, including:
    • Divider1/Divider2/Divider3 charging protocol (Apple proprietary)
    • D+/D- set to 1.2V mode (Samsung proprietary)
    • BC1.2 DCP and CTIS YD/T 1591-2009 charging protocol
  • Reliable POR and LVR performance
  • Multiple package and pin binding options: SOT23-5, SOT23-6
