AH1889-Z-7 Description

Short technical summary and product information.

The AH1889-Z-7 from Diodes Incorporated is a high-sensitivity dual unipolar Hall-effect switch designed for low-voltage applications requiring a quick response time. It operates over a supply voltage range of 1.65V to 3.6V.

 

This device features independent detection of North and South poles, with outputs that switch low when the magnetic flux density exceeds the operate point and remain low until it falls below the release point. The AH1889-Z-7 offers superior temperature stability, extremely low switch-point drift, and enhanced immunity to physical stress due to its chopper-stabilized design. It also provides good RF noise immunity.

 

The Hall-effect switch is packaged in a small, low-profile SOT-553 surface-mount package, minimizing PCB space. Its operating temperature range is -40°C to +85°C.

 

Applications include position and proximity detection for consumer, office, and industrial equipment, open/close detection for home appliances, and contactless switches.
