Product Overview

AH3377-SA-7 is an AH3377 series high voltage low sensitivity hall effect unipolar switch IC designed for proximity, position and level sensing in industrial and consumer home appliances and personal care applications. To support wide range of demanding applications, the design has been optimized to operate over the supply range of 3V to 28V. With chopper stabilized architecture and an internal bandgap regulator to provide temperature compensated supply for internal circuits, the AH3377 provides a reliable solution over the whole operating range. For robustness and protection, the device has a reverse blocking diode with a Zener clamp on the supply. The output has an over current limit and a Zener clamp. Typical applications include position and proximity sensing in consumer home appliances, building automation, office equipments and industrial applications, open and close detect, position detect, level detect, flow meters, contact-less switches.
  • Unipolar operation
  • Single open drain output with over current limit
  • Chopper stabilized design provides: superior temperature stability and minimal switch point drift
  • Chopper stabilized design provides: enhanced immunity to stress
  • Good RF noise immunity
  • Reverse blocking diode
  • Zener clamp on supply and output pins
  • ESD: HBM >6KV
  • 3 pin SOT-23 package
  • Operating temperature range from -40 to 125°C
