RH7902A

RONGHE Microelectronics · USB Converters · SOT-23-6

RH7902A from RONGHE Microelectronics, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DP1 bidirectional Connects to the D+ line of the first USB port for charging protocol handshake. Drives Divider3 (2.7V typical) or other configured protocol voltages.
2 GND power_in Negative supply / ground reference.
3 DP2 bidirectional Connects to the D+ line of the second USB port for charging protocol handshake. Enables independent dual-port protocol negotiation.
4 DM2 bidirectional Connects to the D- line of the second USB port for charging protocol handshake. Drives Divider3 (2.0V typical on DM) or other configured protocol voltages.
5 VDD power_in Positive supply input. Operating range 4.5V to 5.5V (typ 5.0V). LVR threshold ~4.0V; supply current 140uA typical in normal mode.
6 DM1 bidirectional Connects to the D- line of the first USB port for charging protocol handshake. Drives Divider3 (2.0V typical on DM) or other configured protocol voltages.

CAD (KiCad official)

  • Symbol: RH7902A
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: rh7902a-etched.step / rh7902a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rh7902a.step / rh7902a.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: RONGHE Microelectronics datasheet (9 pp, sha256 3b28b7a4e97633ee, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
