MAX9924UAUB/V+T

Sensor And Detector Interfaces Overview

The MAX9924UAUB/V+T is a variable reluctance sensor interface IC designed for automotive position and speed sensing. It operates on a 4.5V to 5.5V supply with a typical current of 2.6mA. The device features a differential input stage, precision amplifier, and comparator with selectable adaptive peak threshold and zero-crossing detection. It generates robust output pulses in noisy environments or with weak signals. The component is housed in a 10-pin uMAX package and is qualified to AEC-Q100 standards for operation between -40°C and +125°C.

Sensor And Detector Interfaces Feature Summary

• Differential input stage provides enhanced noise immunity
• Precision amplifier and comparator allow small-signal detection
• User-enabled internal adaptive peak threshold or flexible external threshold
• Zero-crossing detection provides accurate phase information

Sensor And Detector Interfaces Applications

• Camshaft VRS Interfaces
• Crankshaft VRS Interfaces
• Vehicle Speed VRS Interfaces

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix /V+T indicates automotive qualification and lead-free compliance. Confirm the 10-pin uMAX package matches the design requirements. Check the latest datasheet revision for any updates to electrical characteristics or pin configurations before finalizing procurement specifications.

Sensor And Detector Interfaces Selection Notes

Select this part when interfacing with single-ended or new-generation differential VR sensors requiring high CMRR. The fixed 1V/V gain is suitable for applications not needing adjustable amplifier gain. Ensure the system can accommodate the open-drain output pull-up requirements and that the operating temperature range meets the automotive environment constraints.

Sensor And Detector Interfaces Part Context

This component belongs to the MAX9924–MAX9927 family of variable reluctance sensor interfaces. While the MAX9926 and MAX9927 offer dual channels and additional packages, the MAX9924 provides a single-channel solution in a compact 10-pin form factor. It integrates matched resistors for superior common-mode rejection compared to variants requiring external resistor networks.

Sensor And Detector Interfaces Replacement Considerations

Direct substitutes within the same family include the MAX9924UAUB+ (non-automotive grade). For dual-channel requirements, consider the MAX9926UAEE+/V+. Verify package compatibility and electrical parameter alignment when substituting.
