00 — Overview

What the HAL2041 does

The HAL2041 is a full-polarity, low-power Hall effect switch utilizing mixed-signal CMOS technology and chopper stabilization for stable magnetic switching points. It operates with a supply voltage of 2.0 to 5.5 V, draws an average current of 2.5 uA, and features a 4 KV ESD rating. The device switches at a working point of 60 G and a release point of 25 G with 15 G hysteresis. It is designed for micro-power battery applications, serving as a non-contact switch for flip-phone screen locks, wireless phone reminders, and as a low-duty-cycle alternative to reed switches.
