ET3713A25中文资料Dual-Output Hall Switch数据手册ETEK规格书

描述 Description

The ET3713 is a high sensitivity and high-accuracy Omnipolar Hall effect switch IC that operates at a low voltage and low current consumption. ET3713 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.To achieve a high-density mounting the ET3713 uses a super-small DFN4 package.The ET3713 is suitable for battery powered portable devices such as mobile phones and portable PCs etc. due to its low voltage operation and low current consumption, the average current consumption is only typ. 2.5 μA with a 1.85 V supply.
