Silicon Labs 1 Axis Surface Hall Effect Sensor 1.7V to 5.5V CMOS Technology SOT-23 3-Pin Si7201-B-04-IVR

Silicon Labs Si7201-B-04-IVR is a 1 Axis Surface Hall Effect Sensor designed for precise magnetic field detection with CMOS technology, operating at a low supply voltage range from 1.7V to 5.5V. Packaged in a compact 3-pin SOT-23 package, it is engineered to withstand harsh environments with a wide operating temperature range from -40°C up to 125°C. Its automotive-grade AEC-Q100 qualification ensures high reliability and suitability for demanding applications.

This sensor integrates advanced technologies such as chopper-stabilized Hall elements, low-noise amplifiers, and a 13-bit analog-to-digital converter with comparators. This combination provides high sensitivity and stable output by responding to magnetic fields crossing a pre-programmed threshold. The omnipolar magnetic type allows the sensor to detect either magnetic pole, providing flexible application capabilities.

The device has a fast response time of 8.8 microseconds, enabling effective use in security systems for magnetic detection, position sensing, revolution counting, and tamper indication. Its low supply current of 8.5mA helps reduce power consumption, making it suitable for battery-powered and energy-conscious implementations.

With small dimensions measuring 2.9mm in length, 1.6mm in width, and 1.15mm in height, the SOT-23 package facilitates easy surface mount integration on compact electronic assemblies. The Si720x series provides enhanced options including unipolar switching and latch versions tailored to specific application needs.

Operates reliably across a wide automotive graded temperature range from -40°C to 125°C. Omnipolar magnetic detection for versatile magnetic field sensing. Low current consumption at 8.5mA extends battery life in portable systems.

Fast response of 8.8μs ensures precise magnetic threshold switching. AEC-Q100 certified for automotive-grade reliability and performance. Compact SOT-23 3-pin surface mount package suitable for high-density designs. Advanced integrated components improve sensitivity and reduce noise.
