KMA221

KMA221 Programmable angle sensor Rev. 1 — 16 July 2013 Product data sheet 1. Product profile 1.1 General description The KMA221 is a magnetic angle sensor module. The MagnetoResistive (MR) sensor bridges, the mixed signal Integrated Circuit (IC) and the required capacitors are integrated into a single package. This angular measurement module KMA221 is pre-programmed, pre-calibrated and therefore, ready to use. The KMA221 allows user-specific adjustments of angular range, zero angle and clamping voltages. The settings are stored permanently in a non-volatile memory. 1.2 Features and benefits  High precision sensor for magnetic  High temperature range up to 160 C angular measurement  Single package sensor module with  Analog ratiometric output voltage integrated filters for improved ElectroMagnetic Compatibility (EMC)  Automotive qualified in accordance with  Overvoltage protection up to 16 V AEC-Q100 Rev-G  Programmable user adjustments,  Programming via One-Wire Interface including zero angle and angular range (OWI)  Fail-safe non-volatile memory with write  User-programmable 32-bit identifier protection using lock bit  Independent from magnetic field  Magnet-loss, power-loss and broken strength above 35 kA/m bond wire detection  Ready to use without external  Factory calibrated components NXP Semiconductors 2.
