Variable reluctance sensor interface for engine-speed and position sensing
The MAX9924UAUB+ accepts a differential input from a VR coil and outputs a logic-level pulse train.
The differential input rejects common-mode noise on long leads. The logic output provides a clean digital pulse. The 5 mA supply current sets the regulator budget.
Package and mounting — board-fit details
The MAX9924UAUB+ is supplied in a 10-pin uMAX/uSOP surface-mount package, 3.00 mm body width, 0.118" pitch. That is a small footprint — roughly 3 mm × 3 mm — so it fits on compact sensor-conditioning boards alongside the microcontroller or ECU.
No LTB risk, no cross-reference needed for new production.
