High-Voltage Unipolar Hall-Effect Switches from Diodes Incorporated are Optimized for 3V to 28V Operation
2016-07-19 | ReturnThe devices output switch on with a magnetic south pole of sufficient strength to the part marking surface for SOT23 and SIP3, while SC59 packaged devices work with opposite pole for the same effect.
These Hall-effect switches utilize a chopper-stabilized architecture with an internal bandgap referenced to achieve reliable operation over a wide -40°C to +125°C temperature range with minimal switching point drift. They offer a fast response to power-on and changes in magnetic flux density and feature a reverse blocking diode, Zener clamps on the supply and output, and output over-current limiting to provide device protection and high ESD immunity.
The AH3372 is specified for high-sensitivity requirements, with typical operate and release points of +30G BOP and +20G BRP. The medium sensitivity AH3373 offers +55G BOP and +35G BRP, while the corresponding figures for the AH3376 are +100G BOP and +85G BRP with the AH3377 delivering +115G BOP and +90G BRP. The high-sensitivity AH3782 with its internally pulled-up output has a BOP of +55G and BRP of +35G.
The AH3372, AH3373, AH3376, AH3377 and AH3782 are offered in 3-pin SOT23 and SIP-3 packages, and also an SC59 package that provides the option of switching with a magnetic north pole. For further information, visit the Company’s website at http://www.diodes.com/.
