KMA310

Programmable angle sensor IC

Rev. 3 — 27 February 2019

Product data sheet

1 General description

The KMA310 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.

2 Features and benefits

• High precision sensor for magnetic angular

measurement

• Single package sensor module with

integrated filters for improved electromagnetic

compatibility (EMC)

• Automotive qualified in accordance with

AEC-Q100 Rev-H

• Programmable user adjustments, e.g. zero

angle and angular range

• Fail-safe non-volatile memory with write

protection using lock bit

• Independent from magnetic field strength

above 25 kA/m

• Module ready to use without external

components

• Factory calibrated

• Separate temperature sensor and auxiliary

analog-to-digital converter (ADC) for input

stage supervision

• High temperature range up to 180 °C

• Ratiometric analog output voltage or push pull

output stage compliant with SAE J2716 SENT

using pulse shaping

• Overvoltage protection up to 18 V

• Power-loss detection

• Programming via one-wire interface (OWI)

• 8 × 12-bit original equipment manufacturer

(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
