JYM27278 High Sensitivity Bipolar Latching Ultra-Low Power Hall-Effect Switch Sensor IC
JYM27278 is a high sensitivity bipolar latching ultra-low power Hall-effect switch sensor IC developed by GS-Micro Semiconductor (Shenzhen) Co., Ltd. using 0.18μm BCDMOS process. It features magnetic sensitivity BOP=20Gs, BRP=-20Gs, ultra-low power consumption, wide operating voltage, high stability and strong anti-interference capability. Designed specifically for low-power applications such as consumer electronics and industrial control, it is an ideal alternative to traditional Hall-effect devices.
Core Product Advantages
Excellent ultra-low power performance: only 27μA for 740Hz version, 94μA for 2.6kHz version and 187μA for 5.2kHz version at 3.3V, greatly extending battery life.
0Gs, precise magnetic signal response, minimal impact of mechanical stress on magnetic parameters.
Wide operating voltage range from 1.65V to 5.5V, compatible with low-voltage portable devices and general industrial power supply scenarios.
Built-in temperature compensation and ESD±6kV protection, operating temperature -40℃~85℃, strong environmental adaptability.
Two output options: push-pull output / open-drain output. Miniature packages TO-92S and SOT23-3L, suitable for high-density PCB design.
RoHS compliant, lead-free green device, meeting global market access requirements.

Application Guide
Push-Pull Output: Connect VCC to 1.65V~5.5V power supply, GND to ground, OUT directly to MCU I/O pin. Place a 0.1μF decoupling capacitor between VCC and GND.
Open-Drain Output: Connect a 1~10kΩ pull-up resistor from OUT to power supply. Other connections are the same as push-pull mode, compatible with MCUs of different logic levels.
Ensure magnetic field is aligned with the chip sensing area during installation for stable triggering. Proper ESD protection is required during soldering.
