3-Wire Voltage Mode High-Sensitivity Unipolar Hall-Effect Switch Sensor JYM27112
Product Description – JYM27112 Unipolar Hall-Effect Switch Sensor
The JYM27112 series are high-sensitivity unipolar Hall-effect switch chips designed using advanced BCDMOS process technology. The device integrates an on-chip voltage regulator, under-voltage lockout (UVLO), signal amplifier, temperature compensation, offset cancellation, comparator, output driver, and output current-limiting circuitry. Magnetic parameters are minimally affected by mechanical stress, while the chip exhibits superior EMI immunity and high reliability.
The JYM27112 is optimized for industrial environments with a junction temperature range of -40℃ to 150℃ and an operating voltage range of 2.8V to 24V. It is offered in industry-standard TO-92S and SOT23-3L packages, fully compliant with RoHS (EU) 2015/863 requirements.
