Overview
The AH293-PL-B is a linear Hall-effect sensor IC manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.2V to 28V DC and features an analog voltage output. The device is designed for contactless switching applications, utilizing an on-chip Hall voltage generator and amplifier. It includes a Schmitt trigger to provide switching hysteresis for noise rejection. The component is available in lead-free packages, specifically the SC59 (SOT-23) form factor.
Feature Summary
- Provides analog voltage output proportional to magnetic field strength
- Integrates Schmitt trigger for noise immunity via switching hysteresis
- Supports wide operating voltage range from 4.2V to 28V DC
- Features temperature compensation for stable performance
Applications
- Contactless position sensing
- Linear displacement measurement
- Proximity detection systems
Procurement Notes
Verify the specific suffix 'PL-B' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your assembly process. Cross-reference the ordering part number with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when a linear analog response to magnetic fields is required rather than digital switching. Consider the SC59 package size for space-constrained designs. Verify that the operating voltage range aligns with your system's power supply rails. Evaluate the need for external filtering based on the application's noise environment.
Part Context
This component belongs to the AH293 series of Hall-effect sensors. It is distinct from digital switches like the AH337, offering continuous analog output instead of discrete states. The series is engineered for industrial and automotive environments requiring reliable magnetic sensing without physical contact.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family or from other manufacturers offering similar analog Hall sensors. Ensure replacement parts match the supply voltage range and output characteristics. Verify package compatibility for PCB footprint adherence.
