  • Product introduction

theseHall-effect latchingIt is a sensor IC that is extremely stable and resistant to pressure over a wide range of temperatures, especially for operations up to 150°C. The new Schmitt trigger circuit achieves good performance at high temperatures by compensating for temperature changes in the Hall effect, keeping the operating and release points symmetrical. In addition, the magnetic switchpoint provided by internal compensation is more sensitive to temperature and can counteract temperature-induced magnetic field degradation. The symmetry feature makes the device more suitable for pulse counting applications where duty cycle is a very important parameter. The three basic devices (A1225, A1227, and A1229) are essentially the same except for the magnetic switchpoint.

Each device contains the following components on a single silicon chip: voltage regulator, Hall generator, temperature compensation circuitry, signal amplifier, Schmitt trigger, and buffered open-drain output that draws up to 25 mA. The on-board regulator allows operation with supply voltages from 3.8 to 24 V.

The first character of the designation suffix specifies the operating temperature range of the device. The suffix L refers to –40°C to 150°C. Both packages are available in magnetically optimized packages for most applications. The suffix LT refers to the miniature SOT89/ TO-243AA transistor package for surface mount applications, and the suffix UA is a three-pin ultra-small SIP. Both packages are lead (Pb) free and feature 100% matte tin leadframe plating.
