Product Overview

The VCS2395 is a highly integrated, low-power, two-dimensional magnetic switch sensor. It combines an AMR magnetic sensor with high-precision CMOS processing circuitry in an ultra-small package. The CMOS processing circuit offers precisely controlled BOP/BRP offset voltage compensation and an open-drain output, achieving an industrial operating temperature range (-40~125) and a wide voltage operating range (2.0V~5.5V). Its low current consumption (nA level) makes it suitable for various handheld and battery-powered devices. The two-dimensional magnetic switch can detect magnetic fields from any direction within the chip plane (360 degrees), eliminating the need for specific magnet orientation and significantly simplifying installation and improving system redundancy. Leveraging the high sensitivity of AMR technology, this switch integrates low power consumption, small size, and excellent temperature characteristics, making it a preferred choice for many low-power, high-performance applications.

The VCS2395 is available in two package types: TO-92S and SOT23-3, with corresponding product models VCS2395T and VCS2395S.
