VCS2382

The VCS2381, VCS2382 and VCS2383 are ultra-low power magnetic switch sensors. These devices integrate Anisotropic Magneto-Resistive (AMR) sensor and CMOS signal conditioning circuitry in a small package. CMOS signal conditioning circuitry provides precise control of the Bop/Brp offset voltage compensation circuit and push-pull output within industrial operating temperature range (-40℃ to +125℃), and also provides a wide voltage operating range (2.0V to 5.5V) with low power consumption of Nanoampere level. The low power switches are designed for use in handheld devices or battery powered applications. The two-dimensional magnetic switches can detect the magnetic field of 360 degrees in any direction in the chip plane. Without the magnet being installed in a specific direction, these devices can greatly simplify the installation requirements and improve the system redundancy. Taking advantage of the high sensitivity of AMR, these switches combine low power consumption, small size, and excellent temperature characteristics, making them the first choice for low power, high-performance applications. 

The VCS2381, VCS2382 and VCS2383 are available in a Green SOT-23-3 package.
