ABLIC Inc. 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.

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
