JYM27270 Ultra-Low Power Latching Hall Effect Switch Sensor with All-Pole to Unipolar Memory Feature

JYM27270 is an ultra-low power Hall effect switch with polarity memory latching function. Manufactured via mature 0.18μm BCDMOS semiconductor process, it supports full battery supply voltage from 1.65V to 5.5V. At 3.3V operating voltage, average supply current is as low as 1μA, significantly extending battery life of coin cell and lithium-powered portable devices. The IC automatically identifies magnetic field polarity after power-up and latches the output state permanently, drastically improving immunity to stray magnetic interference compared with conventional Hall devices.

Integrated high-precision temperature compensation circuitry ensures consistent magnetic switching threshold across full operating temperature range. Two output configurations (push-pull & open-drain) are optional with ±6kV human body model ESD protection. Standardized SOT23-3L SMD and TO-92S through-hole packages are fully RoHS compliant. Ideal for magnetic wake-up, flip cover detection and non-contact switch applications in various low-power electronic products.

Two Output Wiring Reference Schemes

1. Push-Pull Output Circuit: Connect VCC to power supply, OUT pin directly to MCU IO port, GND to ground. Place 0.1μF decoupling capacitor parallel to power rail, no external pull-up resistor required.

2. Open-Drain Output Circuit: VCC and GND wiring same as above. A 1k~10kΩ pull-up resistor must be connected to OUT pin, compatible with multi-level voltage MCU systems.

FAQ Frequently Asked Technical & Sourcing Questions

Q1: What is the working principle of JYM27270 memory function? How does it differ from ordinary Hall ICs?

A1: The IC automatically detects N or S magnetic polarity after power-up and latches output level permanently, stray magnetic field cannot flip output falsely. Conventional all-pole Hall devices have no latch function and are easily mis-triggered by surrounding magnetic noise.

Q2: Can the chip run directly from 1.8V coin cells with minimum 1.65V operating voltage?

A2: Yes. Wide voltage range starts at 1.65V, stable operation at full & depleted voltage stage of CR2032 and other coin batteries, with only 1μA quiescent current draw.

Q3: What is the circuit difference between push-pull and open-drain versions?

A3: Push-pull type requires no pull-up resistor and can connect MCU IO directly; open-drain variant needs external 1k~10kΩ pull-up resistor, supporting multi-voltage 3.3V / 5V MCU platforms.

Q4: Can JYM27270 replace AH277 on existing PCB without layout modification?

A4: Full package & pin compatibility, PCB redesign is unnecessary. Minor adjustment of magnet flux density can realize stable operation.

Q5: How to request free samples and bulk quotation?

A5: Contact sales via +86 18018703531 with subject JYM27270 inquiry. Free samples, datasheets and standard reference schematics are available.
