  • Product Introduction

The A1220, A1221, A1222, and A1223 Hall-effect sensor ICs are extremely stable and compressive devices at a wide range of temperatures, especially for applications up to 150°C. Dynamic offset cancellation ensures good performance at high temperatures and reduces residual offset voltages typically caused by device overmolding, temperature dependence, and thermal stress. Each device contains the following components on a single silicon wafer: voltage regulator, Hall generator, small signal amplifier, chopper stabilization, Schmitt trigger, and open-circuit collector output with short-circuit protection that can draw up to 25 milliamps. As long as the south pole has a sufficient magnetic field, the output can be turned on. To turn off the output, you must provide a magnetic field of sufficient strength.

The on-board regulator allows operation from a supply voltage of 3 to 24 V. The advantage of operating at voltages as low as 3 V is that the device can be used in 3-V applications or can be connected in series with the power pin with an additional external resistor for greater protection against high-voltage transients.

Both package types provide magnetically optimized packages for most applications. The LH package is an improved three-pin SOT23W surface mount package, while the UA is a three-pin ultra-small SIP for via mounting. Both packages are lead-free and feature 100% matte tin-plated pin frames.
