Small magnetic sensor IC with a super-low operating current consumption of a mere 160nA and high magnetic sensitivity
TOKYO--(BUSINESS WIRE)--ABLIC Inc. (President: Nobumasa Ishiai, head office: Minato-ku, Tokyo, hereinafter �ABLIC�) today launched the �S-5701 B Series� surface mount TMR (Tunnel Magneto Resistance) sensor IC, a magnetic sensor IC with super-low current consumption, high magnetic sensitivity, long life and an operating current consumption of a mere 160nA.
The �S-5701 B Series� is a TMR sensor IC. However, unlike other MR sensor ICs such as Anisotropic Magneto Resistive (AMR) or Giant Magneto Resistive (GMR) sensor ICs, it features high sensitivity and super-low current consumption (160nA) making it an innovative product that solves the limitations of a conventional reed switch.
Reed Switch Limitations and the TMR Sensor IC Advantages that Solve Them
|
Reed Switch Limitations |
TMR Sensor IC Advantages that Solve Reed Switch Limitations |
|
Vulnerable to vibrations and shock and easily breakable |
As a resin molded product, it has greater resistance to vibrations and shock |
|
More soldering work |
Fewer processes required as it can be soldered together with other components |
|
The magnets used cannot be shrunk beyond a certain size |
About 1/10th the size of a regular reed switch |
|
Current flows as long as the sensor is on making battery life unreliable |
Nano level current consumption extends battery life significantly |
ABLIC has now added a new product, the �S-5701 B Series,� a TMR sensor IC in a �Small, Smart and Simple� product lineup that detects horizontal magnetic fields allowing us to further broaden our customer base by proposing it to customers who are seeking a replacement for the reed switch.
Major Features of the S-5701 B Series
- The IC�s average current consumption is 160nA when using a power supply voltage of 3.3V. About 1/6th of the current consumption of a regular AMR IC
- Operating voltage range: 1.7 to 5.5V, operation temperature range -40 to 125�C and satisfies a wide operating environment
- Employs a super-thin TSOT-23-3S package
- High magnetic sensitivity BOP = 1.0mT products available
Applications
- A reed switch replacement
Examples of products using this IC
- Window open/close sensors, electronic keys, smoke detectors
- Gas meters, water meters, smart meters
