The A1260 sensor IC employs Vertical Hall-effect technology that makes the device extremely temperature-stable and stress-resistant. It is actuated by alternating north and south polarity magnetic fields in plane with the device’s branded face rather than perpendicular to the branded face, as in a traditional Hall-effect sensor. This enables system designers to achieve new mechanical configurations not feasible with traditional planar Hall sensors, including replacing through-hole SIP devices with tiny surface-mount SOT23 ICs, saving space and cost. The device integrates a voltage regulator, Hall-voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, and a NMOS output that can sink up to 25 mA. The on-board regulator permits operation with supply voltages of 3V to 24V. Additionally, the A1260 is qualified to AEC-Q100 standards and includes Zener clamps, output short-circuit protection, and reverse-battery protection.
