It is temperature compensated to keep the trip point stable across the -40°C to 125°C operating range. The switch trips at 18 mT (typical) and releases at 5 mT, giving a 13 mT hysteresis that prevents chatter at the switching threshold. The open-drain output sinks up to 20 mA continuous. ## Supply rail and output drive Minimum supply voltage is 2.7 V, so the part operates from a 3.3 V or 5 V rail with headroom. The 20 mA output current limit means the pull-up resistor and load must be sized to stay within that ceiling — a 1 kΩ pull-up to 5 V draws 5 mA, leaving margin. The switching current is 6 mA typical at 25°C, which is the supply current drawn by the Hall element and the internal bias circuitry when the output is switching. ## Active production and sourcing posture Through-hole package (Bulk) suits prototype builds and low-to-medium volume production where wave-solder or hand-solder assembly is preferred.
