00 — Overview

What the HAL1101 family does

The HAL1101 is a unipolar high-sensitivity Hall effect switch IC utilizing advanced BiCMOS processes for superior temperature stability up to 150°C. It operates across a 2.5V to 28V supply range, drawing 2 mA average current with a 30 mA output limit. The device features a 35 G typical operating point and 25 G hysteresis, available in TO-92S and SOT23-3 packages. Engineers typically use this component for non-contact switching, position detection, brushless motor control, and speed sensing applications where reliable magnetic field detection is required.
