Top Features

Packaging

• Hall-effect Technology allows ease of use for ring magnet and ferromagnetic target sensing 
• Vibration Detection optimized for wheel speed applications allows for blanking of vibration on vibration with minimum delay in output recovery 
• Digital AK Protocol provides speed and direction information, and signal integrity 
• PWM Protocol provides speed and direction information.
• Integrated Capacitor in a single overmolded miniature package provides greater EMC robustness 

The IC is offered in the UB package, which integrates the IC and a high temperature ceramic capacitor in a single overmolded SIP package for enhanced EMC performance. The 2-pin SIP package is lead (Pb) free, with tin leadframe plating.
