AH3382-SA-7

AH3382-SA-7 is a high voltage, ultra-high sensitivity hall effect unipolar switch IC designed for proximity, position and level sensing in industrial and consumer home appliances and personal care applications. For robustness and protection, the device has a reverse blocking diode with a Zener clamp on the supply. The output has an overcurrent limit and a Zener clamp. When the magnetic flux density (B) perpendicular to the package is larger than the operate point (BOP) the output is switched on (pulled low) and is held on until the magnetic flux density B is lower than the release point (BRP). The output remains switched off for north pole fields or no magnetic fields. Applications include open and close detection, position detection, level detection, flow meters, and contactless switches.

• Internally pull-up resistor on the output with over current limit
• 3.0V to 28V operating voltage range
• Chopper stabilized design provides superior temperature stability
• Minimal switch point drift, enhanced immunity to stress
• Good RF noise immunity, reverse blocking diode
• Zener clamp on supply and output pins
• ESD: HBM > 6kV
• Output leakage current (when output is off) is <0.1µA typ at VOUT = 28V, B < BRP, output off
• SOT23 package
• Operating temperature range from -40 to +125°C
