Product details
Overview
KMA200,115 from NXP Semiconductors is a programmable magneto-resistive angle sensor IC integrating MR sensing elements and mixed-signal signal processing in a single SOT637 package. It delivers <0.05° resolution, operates from −40 °C to +160 °C, supports SPI programming of zero point and max angle (up to 180°), and provides dual analog or digital output modes for automotive throttle, steering, and industrial rotary position sensing.
For engineers reviewing the KMA200,115 datasheet, KMA200,115 pinout, KMA200,115 application, or KMA200,115 equivalent, this page details its CORDIC-based angle computation, EEPROM-programmable diagnostics, ratiometric analog outputs with four configurable characteristics, SPI-compatible 24-bit digital output with parity, and integrated overvoltage/reverse-polarity protection - all validated for high-reliability motor control and safety-critical motion feedback systems.
Technical Context
The KMA200,115 uses two orthogonal MR bridges feeding instrumentation amplifiers and ΣΔ-modulators, followed by decimation filters and an on-chip calibration microcontroller executing the CORDIC algorithm to compute mechanical angle. Its digital core includes watchdog timer, oscillator fail-safe circuit, and CRC-16 validation of EEPROM configuration constants.
Angle output is delivered either as dual ratiometric analog voltages (VOUT1 standard, VOUT2 programmable in mode 1–4) or as 24-bit SPI data (13-bit angle + error flag + 7-bit temperature + parity bits). Diagnostics monitor input stage magnitude, output stage fidelity via auxiliary ADC, temperature thresholds, and power integrity - signaling faults via high-impedance analog outputs or diagnostic bits in digital mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable angle sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMS AS5055A | 14-bit SPI-only output; no analog outputs; lower temp range (−40 °C to +125 °C); no integrated EEPROM programming interface. | Lacks dual-output redundancy and ratiometric analog capability; requires external MCU for calibration storage. | Choose for cost-sensitive, digital-only designs where full diagnostic coverage and extended temperature are not required. |
| Texas Instruments TMAG5170 | 3-axis Hall-based sensor; 16-bit SPI output; supports XYZ field vector reporting; higher resolution (0.004° typical); no analog outputs. | Provides 3D field data for advanced algorithms (e.g., tilt compensation); lacks built-in CORDIC angle computation and analog output stages. | Prefer when multi-axis field analysis or ultra-high resolution is needed, but accept added MCU processing load and absence of analog fallback. |
Compared with AMS AS5055A and TI TMAG5170, the KMA200,115 uniquely combines dual ratiometric analog outputs with SPI digital interface, on-chip CORDIC computation, EEPROM-based field programmability, and −40 °C to +160 °C operation - making it optimal for safety-critical, thermally demanding applications requiring hardware-level redundancy and minimal external components.

FAQ
What output modes does the KMA200,115 support, and how are they configured?
The KMA200,115 supports both analog and digital output modes, selected via EEPROM configuration. Analog mode provides dual ratiometric outputs: VOUT1 (standard 5–95% VDD) and VOUT2 (programmable as inverted, half-range, comparator, or high-Z). Digital mode delivers 24-bit SPI data (13-bit angle + error flag + 7-bit temperature + parity bits). Configuration is performed using the Serial Peripheral Interface and stored permanently in on-chip EEPROM - no external memory required. The KMA200,115 retains settings across power cycles and operates immediately upon power-up.
How does the KMA200,115 implement diagnostics, and what failure conditions does it detect?
The KMA200,115 performs continuous online diagnostics covering input stage (MR bridge signal magnitude), output stage (via auxiliary ADC comparison), oscillator health, watchdog timer, EEPROM CRC integrity, overtemperature (warning and shutdown thresholds), overvoltage, and reverse polarity. In analog mode, errors force outputs into high-impedance state, with external pull-up/down resistors driving them into diagnostic voltage ranges. In digital mode, errors set a dedicated flag and encode fault type in LSBs. All diagnostics are configurable via EEPROM control words - allowing tailoring to specific system safety requirements. The KMA200,115 implements these functions autonomously without MCU intervention.
What is the accuracy and resolution performance of the KMA200,115 across temperature?
The KMA200,115 achieves better than 0.05° angle resolution in analog mode and 0.022°/LSB in digital mode. Its total angle error includes ±1.65° linearity deviation and ±0.64° temperature drift (−25 °C to +125 °C, 3σ). Microlinearity is ±0.1°, hysteresis ≤0.088°, and output noise is ≤0.1° peak-to-peak. These specifications are guaranteed over the full −40 °C to +160 °C operating range, with internal temperature compensation applied in real time using on-chip sensor data and EEPROM calibration constants. The KMA200,115 maintains this accuracy without external recalibration.
Can the KMA200,115 be used in safety-critical automotive applications, and what features support ASIL compliance?
Yes, the KMA200,115 is designed for ASIL-B relevant applications such as throttle and steering angle sensing. It supports functional safety through dual-output plausibility checking (e.g., |VOUT1 + VOUT2 − VDD| ≤ ±0.5% VDD), comprehensive diagnostics with configurable fault response, CRC-16 validation of EEPROM configuration, watchdog timer with fail-safe feed sequence, and overtemperature shutdown. Its −40 °C to +160 °C qualification, robust pin protection, and pre-calibrated, ready-to-use operation reduce integration risk. The KMA200,115 provides the hardware foundation for ISO 26262-compliant system design when combined with appropriate software safety mechanisms.
What packaging and environmental qualifications does the KMA200,115 have?
The KMA200,115 is housed in a SOT637 plastic single-ended multi-chip package with 5 in-line leads and 6 interconnections, optimized for surface-mount assembly and thermal dissipation in high-temperature environments. It is qualified per AEC-Q100 Grade 0 (−40 °C to +160 °C), with 1000-hour lifetime validation at 160 °C. The device features integrated overvoltage protection (−16.5 V to +32 V transient), reverse polarity protection, and short-circuit immunity on all pins - eliminating need for external protection components. The KMA200,115 meets stringent automotive reliability standards while maintaining full specification performance across its entire operating range.
