RH7901/RH7902 USB Charging Protocol Controller with 4.5V~5.5V Operating Voltage and Dual-port Control for Multiple USB Charging Protocols
RH7901/RH7902 is a USB charging protocol port control IC. It can automatically identify the type of charging device and establish a handshake with the device through the corresponding USB charging protocol, enabling it to obtain the maximum charging current while protecting the charging device and saving charging time.
Application scope: Portable power banks, portable chargers, vehicle chargers Wait.
- Operating Voltage: 4.5V to 5.5V
- Dual-port control function (RH7902): Can independently support two USB charging protocol detection simultaneously
- Supports multiple USB charging protocols, with automatic switching among them, including:
- Divider1/Divider2/Divider3 charging protocol (specific for Apple)
- D+/- set to 1.2V mode (specific for Samsung)
- BC1.2 DCP and CTIS YD/T 1591-2009 charging protocols Agreement
- Reliable power-on reset (POR) and low-voltage reset (LVR) performance
- Various packaging and pin configurations: SOT23-5, SOT23-6
