SD3327 Datasheet PDF - SHOUDING Shouding Semiconductor

Overview
SD3327 is a dual-channel capacitive touch Table lamp control chip, can control two channels with one-key touch output.
SD3327 application circuit is simple, only need two peripherals A capacitor and a resistor can realize the touch control function can, easy to process, low cost, and the use of capacitive The detection method can realize the separation between the touch switch and the control circuit away, safe and reliable.
