Core Advantages: High Sensitivity for Precision Magnetic Sensing

1. High Sensitivity & Low Magnetic Trigger, Precise Response in Low Magnetic Fields

JYM27113 features 70Gs operate point (BOP) and 50Gs release point (BRP), enabling accurate capture of weak magnetic signals to meet requirements for low-field sensing and short-distance detection. With a magnetic hysteresis of 10~30Gs, it effectively avoids false triggering from minor magnetic fluctuations, ensuring stable detection accuracy for high-sensitivity industrial applications.

2. Full Wide Voltage & Temperature Range, Stable Operation in Extreme Environments

Supports 2.8V~24V ultra-wide operating voltage, compatible with 3.3V/5V/12V/24V industrial power systems without additional power conditioning circuits, greatly simplifying hardware design. Junction temperature range is -40℃~150℃, suitable for high and low temperature industrial environments. Built-in temperature compensation for magnetic switch points ensures minimal drift of operating thresholds over temperature and voltage variations.

3. Low Power, High Integration, Easy Development & Application

Typical operating current is only 1.8mA, reducing system power consumption for battery-powered and low-power industrial equipment. The chip integrates voltage regulator, under-voltage lockout, signal amplifier, offset compensation, output driver, and current limiting protection. Minimal impact from mechanical stress on magnetic parameters allows direct connection to MCU GPIO with minimal external components, shortening development and debugging cycles.

4. Multiple Protections & High Immunity, Durable in Industrial Scenarios

Built-in over-temperature protection, reverse power protection, output current limiting protection, with 43mA output current limit to prevent damage from short circuits, overcurrent, and reverse connection. ESD protection reaches ±8kV, with excellent EMI performance, ensuring stable operation in high-interference environments such as industrial inverters and motors, improving equipment reliability and service life.
