RH6617

RONGHE Microelectronics · LED Drivers · SOP-8

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.
