KMI174X NXP

( KMI17/4 7 2 6 Rotational speed sensor Rev. 1 1 September 2014 Product data sheet 1. Product profile 1.1 General description Based on the Anisotropic MagnetoResistive (AMR) effect, the KMI17/4 detects the rotational speed of passive target wheels (i.e. having ferromagnetic teeth). This design delivers secure speed information over a wide range of speed, air gap and temperature. It delivers the speed information via a current protocol at the supply pins. CAUTION Do not press two or more products together against their magnetic forces. 1.2 Features and benefits System in package Two wire standard current interface Large range of operating terminal voltage Wide temperature range High ElectroStatic Discharge (ESD) protection Very low jitter Automotive qualified in accordance with AEC-Q100 Rev-G (grade 0) Customer Production Test Mode (CPTM) 1.3 Quick reference data Table 1.
