Linear Hall sensor AH49E

Product catalog summary

Features

Rated working voltage: 4.5 V to 6.5 V.
Operating temperature range: -40℃ to 125℃.
Rail to Rail voltage output with a rated output current of 6 mA.
Available in various package forms and outer packings.
No mechanical contact, ensuring high reliability and safety.
Compliant with EU RoHS and REACH regulations.

Outline

The AH49E sensor operates through linear, nonlinear, and saturation areas as magnetic induction increases. Without a magnetic field, the output voltage is half of Vcc. The output voltage decreases with the 'N' pole and increases with the 'S' pole until saturation is reached.

Block Diagram

The AH49E is an analog signal output Hall IC with built-in reverse voltage protection, voltage regulators, temperature compensation, and signal amplification circuits, ensuring stable operation across a wide voltage and temperature range.

Limit Parameters

Storage Temperature: -55℃ to 175℃.
Supply Voltage: 4.0 V to 6.0 V.
Magnetic Induction: Unlimited.

Electrostatic Grade

Withstands electrostatic compression greater than ±6kV.

Operating Conditions

Supply Voltage: 4.5 V to 5.5 V.
Operating Temperature: -25℃ to 85℃.
Output Current: Up to 6 mA.

Electromagnetic Characteristics

Stationary Voltage: 2.3 V to 2.7 V at VCC=5V.
Stationary Voltage Drift: -15 mV to 15 mV at VCC=5V, TA=125℃.
Supply Current: 3 mA to 8 mA at VCC=5V.
Sensitivity: 12.5 mV/mT to 20.5 mV/mT at VCC=5V, TA=25℃.
Sensitivity Drift: 0.06℃/% to 0.18℃/%.
Linear Area: -90 mT to +90 mT.

Package Outline

Linear Hall Sensor AH49E The sensor will pass linear area /nonlinear area/ saturation area during the magnetic induction increases. When there is no magnetic field that applies in sensor (B=0), when the output voltage of sensor is only half of Vcc (Vcc/2); when “N” pole faces mark surface of sensor, and be closed to it gradualy (B→-∞）,the output voltage begins to decrease, and the voltage doesn’t reduce with the increased magnetic field; When the “S” pole of magnet faces the mark surface of the sensor and is closed to sensor gradualy （B→+∞）, the output voltage of sensor begins to increase, and...
