RH6617 from RONGHE Microelectronics, in a SOP-8. 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 | MOD2 | input | Mode configuration bit 2. CMOS input with internal pull-up (default logic high = VDD). Combined with MOD1, selects one of four output modes (single/dual channel, brightness memory, stepless vs 3-level dimming). |
| 2 | CMOD | bidirectional | Touch sensing sampling capacitor pin. Requires an external 15-47 nF capacitor to GND (X7R or NPO recommended). Larger capacitance increases touch sensitivity; must be placed close to the IC and away from heat/power sources. |
| 3 | VDD | power_in | Positive supply. Operating range 2.4 V - 5.5 V (typ 3.0 V). Standby average current ~15 µA @ 3 V. Decouple with capacitor placed close to IC. |
| 4 | GND | power_in | Negative supply / ground reference. |
| 5 | TCH | bidirectional | Touch sensing input. Connects to the external touch pad, typically through a series resistor Rs (>5 kΩ recommended) for ESD/noise immunity. Detects short and long press gestures for on/off/toggle and brightness dimming. |
| 6 | MOD1 | input | Mode configuration bit 1. CMOS input with internal pull-up (default logic high = VDD). Combined with MOD2, selects the output mode. |
| 7 | TO1 | output | PWM output channel 1 (push-pull CMOS). Drives LED load (typically via a current-limiting resistor and driver transistor). Sink drive IOL ≈ 38 mA @ 3 V (65 mA @ 5 V); source drive IOH ≈ 13 mA @ 3 V (32 mA @ 5 V). PWM 24 kHz stepless or 32 kHz 3-level. |
| 8 | TO2 | output | PWM output channel 2 (push-pull CMOS). Second dimming channel with same drive characteristics as TO1. May be left unconnected in single-output applications. |
