RH791A

RONGHE Microelectronics · USB Converters · SOT-23-5L

RH791A from RONGHE Microelectronics, in a SOT-23-5L. 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 NC unconnected No connect. Pin is not internally bonded; leave floating or tie as convenient during PCB layout.
2 GND power_in Negative supply / ground return for the device. Connect to the system 0 V rail.
3 VDD power_in Positive supply, 4.5-5.5 V (typ. 5.0 V). Typical operating current 140 uA. A ~500 Ω-1 kΩ series resistor from VBUS and a 1 uF bypass cap to GND are recommended to guard against AC-DC overshoot up to 7-9 V.
4 DP bidirectional USB D+ data line to the downstream USB connector. Driven to 2.7 V (Divider3, 12 W Apple) typical; also supports 1.2 V (Samsung), short-to-DM (BC1.2 DCP / CTIS YD/T 1591-2009). ESD >6.5 kV HBM.
5 DM bidirectional USB D- data line to the downstream USB connector. Driven to 2.7 V (Divider3, 12 W Apple) typical; also supports 1.2 V (Samsung), short-to-DP (BC1.2 DCP / CTIS YD/T 1591-2009). ESD >6.5 kV HBM.

CAD (KiCad official)

  • Symbol: RH791A
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: rh791a-etched.step / rh791a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rh791a.step / rh791a.glb are the bare package body.

Provenance

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

  • Datasheet: RONGHE Microelectronics datasheet (7 pp, sha256 858bd6993b5b7770, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
