AH Hall Sensor Selection Guide

Product catalog summary

Overview: This document provides a selection guide for the AH series Hall ICs, detailing various types including Bipolar, Unipolar, Omnipolar, and Linear Hall ICs. Each type is characterized by specific manufacturing techniques, output states, and operational parameters.

Bipolar Hall ICs: These ICs are available in packages such as SOT23, SOT89, and TO92, with a supply current of 4 mA and a load capacity of 25 mA. They operate within a voltage range of 4.5 to 24 V and are suitable for temperatures from -40 to 150°C. Key parameters include BOP (Operate Point), BRP (Release Point), and BH (Hysteresis), with values varying across models.

Unipolar Hall ICs: The document notes typical values for these ICs, tested at a supply voltage of 3.3V and an ambient temperature of 25°C. Specific models and their parameters are not detailed in the provided text.

Omnipolar Hall ICs: These ICs, such as the AH3661 and AH3662, utilize CMOS technology and are available in SOT23 and TO92 packages. They have a supply current ranging from 1.0 to 6.0 μA and operate at voltages between 1.65 to 5.5 V. They are designed for temperatures from -40 to 85°C, with BOP and BRP values indicating their magnetic sensitivity.

Linear Hall ICs: These ICs, including models like AH3503 and AH3519, provide analog output and are available in SOT23 and TO92 packages. They operate with a supply current of 6 mA and a voltage range of 3.5 to 10.5 V. Sensitivity is measured in mV/mT, with linear areas specified for each model, suitable for temperatures from -40 to 125°C.

Other Hall ICs: Additional models such as AH4158 and AH4059 are noted, with specifications including a supply current of 6 mA and a load capacity of 500 mA. They operate within a voltage range of 4.5 to 24 V and are suitable for temperatures from -40 to 85°C.

Conclusion: The document provides a comprehensive guide to selecting the appropriate Hall IC based on specific operational requirements, highlighting key parameters and conditions for optimal performance.
