A1101EUA-T General Description

Allegro MicroSystems has introduced the A1101EUA-T, a micropower magnetoresistive sensor that delivers exceptional performance in magnetic sensing applications. Its innovative Wheatstone bridge circuit design ensures a linear output proportional to the applied magnetic field, providing accurate and stable measurements. With an operating voltage range of 3.8V to 30V and a quiescent current consumption of only 1.6mA, this sensor is remarkably energy-efficient and suitable for a wide range of low-power devices. Its small surface-mount package, measuring just 1.6mm x 1.6mm, allows for seamless integration into space-constrained designs. Additionally, the A1101EUA-T features a high sensitivity of 1mV/V/Gauss, enabling precise detection of magnetic fields. Its robust built-in protection against reverse battery connection, overvoltage, and reverse current enhances durability and reliability. Moreover, the sensor offers a programmable set/reset threshold, allowing for customization to meet specific application requirements. With a wide operating temperature range of -40°C to 85°C, the A1101EUA-T ensures consistent performance even in harsh environments
