Technical Specifications

Applicable Applications

• Consumer equipment (home appliances, AV equipment, communication equipment, information equipment, office equipment, household robotics) - functions not directly related to protection of human life and property.
• Industrial equipment (base stations, manufacturing equipment, industrial robotics, measurement equipment) - functions not directly related to protection of human life and property.
• Medical equipment (GHTF Class A and B) - functions not directly related to protection of human life and property.
• Security equipment (door/window sensors, smart keys, meter tampering detection) - functions not directly related to protection of human life and property.

Unsuitable Applications

• Applications listed in Limitation of applications in this document.

Marking Example

: Control code (One alphabetic character)
: Manufactured year (Last digit of the year)
: Manufactured month (1-9: 1-9, 10-12: X, Y, Z)

Reference Mount Pad

Note: The land pattern is an example. Please evaluate soldering paste and reflow conditions.

Magnetic Field Application Direction

Note: Ensure the sensing direction of the sensor aligns with the applied magnetic field direction.

Block Wiring Diagram

Refer to the document for the block diagram.

Magnetic Electric Conversion Characteristic

ON/OFF switching depends on the intensity of the applied magnetic field (Positive logic).

Timing Diagram

Note 1: The AMR element is driven by an intermittent switch circuit. VOUT change timing is within the ICC on period. Note 2: Consider the speed of magnetic field change against the intermittent operation in your design.
