General description

The KMA321/A is a single channel magnetic angle sensor. Magnetoresistive (MR)

sensor bridges and mixed signal IC are integrated into a single package. The module

has integrated filters and is optimized for PCB-less designs. The IC allows user-specific

adjustments of angular range, zero angle, and clamping voltages. The settings are

stored permanently in a non-volatile memory (NVM). The programmable angle sensor is

pre-programmed, pre-calibrated and therefore, ready to use.

Features and benefits

? High precision sensor for magnetic angular

measurement

(OEM) code registers for identification (ID)

? ISO 26262 ASIL-C capable, safety element

out of context (SEooC)

? Multipoint calibration (MPC) with

17 equidistant or seven free selectable

calibration points

? Low latency
