00 — Overview

What the SC2402 does

The SC2402 is a high-sensitivity digital bipolar Hall effect sensor utilizing mixed-signal BiCMOS technology. This device integrates a regulator, dynamic offset cancellation system, Schmitt trigger, and open-drain output driver within a single package. It operates across a wide voltage range of 2.5V to 18V and supports temperatures from -40°C to +125°C. Available in TO-92S, SOT23-3L, and DFN1616-6L packages, the sensor features a high chopping frequency and low power consumption. Engineers typically use it for applications requiring precise magnetic field detection, such as in power tools, flow meters, valve status monitoring, brushless motors, and proximity switches.
