车规 ET3715A30
General Description
The ET3715A30 is a high sensitivity and high-accuracy Omnipolar Hall effect switch IC that operates at an ultra-low voltage and low current consumption. 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 ET3715A30 uses a super-small DFN4 package.
The ET3715A30 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. 12μA with a 1.2V supply.
