Overview

RH6618 is a single-channel capacitive touch-sensing PWM output dimming IC. RH6618 supports touch functionality through dielectric isolation (e.g., glass, acrylic, plastic, ceramic), ensuring high safety. Featuring a built-in voltage regulator, power-on reset/under-voltage reset, and an ambient adaptive algorithm, the RH6618 delivers excellent EMI immunity. RH6618 applications: touch-dimmable LED desk lamps, touch-dimmable LED wall lamps, and other touch-based products requiring PWM output control.

Applications

Touch-dimming LED desk lamps
Touch-dimming LED wall lamps
Other touch-based products requiring PWM output control

Key features

Operating voltage: 2.4V~5.5V
Standby average current 15uA@3V
0.5s fast power-on initialization
Ambient adaptive function for rapid response to scenarios such as power-on before medium coverage and touch power-on
Reliable POR and LVR performance
PWM output frequency 25KHz (stepless) / 33KHz (3-level dimming), effectively reducing flicker
Package types: SOP8, DIP8, SOT23-6
