JYM27111 3-Wire Wide-Voltage Ultra-Ultra High Sensitivity Unipolar Hall Switch IC
Product Description
The JYM27111 series is a highly reliable ultra-ultra high sensitivity unipolar hall switch IC fabricated via advanced 0.18μm BCDMOS wafer technology. The monolithic die integrates complete analog & digital functional circuits: voltage regulator, under-voltage lockout (UVLO), signal amplifier, offset cancellation, magnetic switching threshold temperature compensation, voltage comparator, output driver and output current limiter. Mechanical stress causes negligible magnetic parameter drift, delivering superior EMI immunity and long-term operational stability under wide high-low temperature industrial & automotive lighting working conditions.
It supports universal industrial DC supply from 2.8V to 24V, with operating junction temperature spanning -40℃ up to 150℃, perfectly matching harsh high-temperature environments of miniature industrial equipment, portable lithium power tools and small automotive lamp assemblies. Two standardized packages are available: TO-92S through-hole and SOT23-3L surface mount device. Both packages fully comply with RoHS (EU) 2015/863 environmental directive to meet global export compliance requirements for all lighting, motor and consumer OEM manufacturers.

Important Notice: Never input supply voltage over the maximum 24V rating, overvoltage will cause permanent irreversible IC damage. SOT23-3L SMD package is recommended for enhanced PCB thermal dissipation under continuous high-temperature operation of small portable power tools & mini BLDC motors. This model features industry-low BOP=25Gs, specially optimized for tiny magnet, long gap weak magnetic short-distance proximity detection applications.

Two Sets of Standard Typical Application Circuits
Application Circuit 1: Basic Standard Wiring Reference Schematic
Recommended load resistance RL: 1kΩ~10kΩ, power supply decoupling capacitor CP=10nF, output filter capacitor CL=4.7nF. Mount all capacitors as close as possible to IC pins to suppress high-frequency switching noise and stabilize weak magnetic trigger performance.
Application Circuit 2: Anti-EMI Noise Suppression Solution for Disturbed Power Rails
Designed for miniature equipment with severe BLDC motor EMI interference & large power supply ripple. Add series current-limiting resistor R1=100Ω on VDD input, parallel CP=10nF between supply pin and GND, parallel CL=4.7nF between output pin and GND. Place all capacitors adjacent to IC pins to greatly improve system EMI immunity and avoid false trigger under weak magnetic signals. Recommended parameters: R1=100Ω, CP＝10nF, CL＝4.7nF.
Installation Operation Guidelines: Wear ESD wrist strap throughout soldering process for full electrostatic discharge protection. Align the IC sensing surface facing the magnet pole for consistent stable trigger output. This ultra-ultra high sensitivity version reliably responds to weak magnetic fields with tiny magnet and large air clearance. Add large-area copper pour on PCB layer for thermal dissipation under long-term continuous high-temperature working conditions.

FAQ Common Technical & Global Procurement Inquiries
Q1: Can JYM27111 be directly powered by 24V industrial DC power supply?
A1: Yes, the IC maximum supply rating is 24V and runs stably under no-load 24V input. For small BLDC motor equipment with frequent voltage spikes, an RC filter circuit is strongly recommended to prevent IC breakdown and weak magnetic false triggering caused by high-voltage pulses.
Q2: Can the IC operate continuously inside high-temperature mini motor housings at rated 150℃ junction temperature?
A2: 150℃ only serves as transient peak rating. For long-term continuous operation above 140℃ junction temperature, select the SOT23 SMD package and expand PCB copper pour area for better heat dissipation performance.
Q3: What is the difference between JYM27111 / JYM27112 / JYM27113 / JYM27114, how to select the suitable model?
A3: JYM27111 BOP=25Gs ultra-ultra high sensitivity, ideal for tiny magnets & long air gap weak magnetic detection; JYM27112 BOP=40Gs ultra-high sensitivity; JYM27113 BOP=70Gs medium sensitivity; JYM27114 BOP=120Gs high threshold with superior stray magnetic noise rejection, suitable for high-field large BLDC motor environments.
Q4: Will reversed VDD & GND polarity instantly destroy the hall IC?
A4: Built-in reverse polarity protection avoids damage during short-duration reverse connection. Long-term reverse power supply is not suggested, which will shift electrical parameters and degrade weak-magnetic trigger accuracy significantly.
Q5: How to request free samples, official datasheets and reference schematic files?
A5: Contact our global sales hotline +86 180 1870 3531, mark part number JYM27111. We supply free original factory engineering test samples, complete official datasheets and two sets of standard hardware application schematics upon client request.
