Plano, Texas – January 11th, 2017 – Targeting automotive applications, Diodes Incorporated has introduced a new family of high-voltage, unipolar Hall effect switch ICs that are qualified to AECQ100 Grade 0 and offer a range of operating sensitivities. Designed for position and proximity sensing in applications such as seat buckle fastening, door and trunk open, close and lock function detection, and the position of gear stick, wipers, mirrors and valves, the AH336xQ and AH339xQ series contactless switches meet end-use requirements both within the vehicle cabin and engine compartment.
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, ranging from a highly sensitive 30G BOP device to a low-sensitivity 275G BOP version, address the needs of a wide range of automotive applications. The BOP and BRP thresholds provide a tight operating window with adequate hysteresis for reliable operation, while a low temperature coefficient ensures the stability of the switching points. 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, providing a robust solution for use in the intended harsh automotive environment. Reliability and ease of handling during end-equipment manufacture is further enhanced by a reverse-blocking diode and Zener clamps on the supply and output pins; protection from ESD exceeds 8kV HBM and 2kV CDM. An open-drain output provides end-design flexibility and low-current consumption with an accurate current limit.
The AH336xQ and AH339xQ series devices are offered in small footprint, 3-pin SC59, SOT23 and SIP-3 packages and are all priced at $0.25 each in 10,000 piece quantities.
