SL130x Series: High-Performance, Low-Power, Omnipolar TMR Switch Sensor
Product Overview
The SL130x series is an integrated Tunnel Magnetoresistance (TMR) and CMOS magnetic switch sensor designed for high-precision, high-speed, and low-power magnetic field detection. It offers high sensitivity and is suitable for industrial and consumer electronics applications requiring magnetic switch functionality. The sensor detects magnetic fields parallel to the chip surface, providing an output signal when the magnetic field strength exceeds the operating point (BOP) and returning to its original state when it drops below the release point (BRP). With a wide operating voltage range (1.8V to 5.5V), extended operating temperature range (-40 to 125), and options for various magnetic thresholds, operating frequencies, and package types (SOT-23-3L, TO-92S), the SL130x series offers flexibility for diverse applications. Its omnipolar detection capability and ultra-low power consumption make it an ideal choice for battery-powered devices and energy-efficient designs.
