Product Overview

    TMR1302BL is an ultra-low power, full-pole magnetic switch with linear magnetic field output, utilizing Tunneling Magnetoresistance (TMR) and CMOS technologies. The TMR1302BL chip integrates a TMR sensor and signal processing circuit internally. It outputs a switch signal while simultaneously providing a linear magnetic field strength signal through a single terminal, allowing it to be used as both a magnetic linear sensor and a switch sensor.

    TMR1302BL is an ideal choice for numerous low-power, high-performance applications due to its wide operating voltage range, microampere-level operating current, high response frequency, and wide operating temperature range. The packaging form of TMR1302BL is SOT23-5, and the corresponding product model is TMR1302BLS.
