General Description
The ET3725A30 is a high sensitivity and high-accuracy Omnipolar Hall effect switch IC that operates at an ultra-low voltage and low current consumption. ET3725A30 has two CMOS output terminal for N and S pole. The output voltage will be pulled low when this IC detects the magnetic flux density is larger than operate point(BOPN/BOPS) and the output voltage will recover to high until the magnetic flux density is smaller than the release point(BRPN/BRPS). Using this IC with a magnet makes it possible to detect the open / close status in various applications.
