KMA210 Programmable angle sensor Rev. 2 — 7 December 2011 Product data sheet 1. Product profile 1.1 General description
The KMA210 is a magnetic angle sensor module. The MagnetoResistive (MR) sensor bridges, the mixed signal Integrated Circuit (IC) and the required capacitances are integrated into a single package. This angular measurement module KMA210 is pre-programmed, pre-calibrated and therefore, ready to use. The KMA210 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 Ratiometric analog 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 Document Outline 1.
