Product Description
Allegro Microsystems A1102EUA-T Through Hole Hall Effect Sensor Ultra Mini SIP 3-Pin is a high-precision motion sensor IC designed for industrial, automotive, and electronics applications requiring reliable magnetic field detection. Utilizing advanced BiCMOS technology, it ensures fast power-on time and low noise operation.
This sensor integrates a voltage regulator to allow operation across a broad supply voltage range from 3.8 V to 24 V, with protection circuitry that tolerates up to ±30 V absolute maximum voltage. The device features a unipolar magnetic sensor type and a small form factor ultra-mini SIP package, simplifying through-hole PCB mounting.
Its design incorporates unique Hall element geometries and low offset amplifiers, significantly reducing residual offset voltage typically caused by device over-molding and thermal stress. The device programming occurs after packaging to enhance magnetic switch-point accuracy, mitigating the effects of mechanical stress during assembly.
The sensor offers a 4 µs response time and consumes a low supply current of 7.5 mA, enabling energy-efficient operation in embedded environments. It is rated for operation between -40°C and 85°C, making it suitable for harsh automotive and industrial conditions compliant with AEC-Q100 standards. Pb-Free construction aligns with environmental compliance directives.
The sensor is ideal for automotive speedometers, position sensing, brushless DC motor commutation, and contactless switching applications. Its robust electrical characteristics and solid-state reliability provide stable performance over full operating temperature and voltage ranges.
On-board reverse polarity protection and high electromagnetic compatibility assure durability in complex systems. The compact 3-pin SIP package with a length of 4.09 mm, width of 1.52 mm, and height of 3.02 mm facilitates compact and space-saving PCB layouts.
Designed and manufactured to meet high automotive reliability standards, providing long-term operational stability.
