ET604

General Description

The ET604 series products are novel switch microphone chips designed for electronic atomization devices. Their standout feature is the PowerFree™ operation mode, eliminating the need for power cables in traditional switch microphones and thereby reducing costs. The ET604, on the other hand, is a traditional preset sensitivity product with a built-in uniform air pressure sensitivity threshold. When the air pressure changes reach the preset threshold, an output signal is triggered. This series of products offers a choice of positive or negative suction trigger directions, accommodating microphones of different structures. It supports two levels of suction force determination, distinguishing between light and heavy suction through square wave outputs at two different frequencies, with a standby current of less than 5μA.
