Hall switch family spans 10-fold sensitivity range
The AH336xQ and AH339xQ are activated when a magnetic south pole of sufficient strength is presented perpendicular to the package. These Hall effect ICs switch on when the magnetic flux density exceeds the defined operating threshold (BOP) and switch off when the flux density falls below the release threshold (BRP). Ten sensitivity options range from a 30G BOP device to a low-sensitivity 275G BOP version. A chopper-stabilized design minimizes offsets with fast power on and response times, which are particularly important in reducing sensing delays and accuracy errors. In addition to the SOT23 package, the AH3362Q/3Q/5Q/6Q and AH3390Q are also offered in an SC59 package that provides the opposite polarity for magnetic flux detection.
The AH336xQ and AH339xQ Hall effect ICs are designed to operate over a wide 3.0V to 28V supply voltage range and over a -40°C to +150°C temperature range. In 3-pin SC59, SOT23 and SIP-3 packages they are all priced at $0.25 (10,000).
