Product details
Overview
KMZ60,115 from NXP Semiconductors is a magnetoresistive (MR) angle sensor with integrated instrumentation amplifier, designed for rotor position detection in BLDC motors with even-numbered pole pairs. It delivers ratiometric cosine and sine analog outputs (VOUT1/VOUT2), operates from −40 °C to +150 °C, supports up to 25,000 r/min magnetic field rotation, and features temperature-compensated amplitude and power-down mode.
For engineers reviewing the KMZ60,115 datasheet, KMZ60,115 pinout, KMZ60,115 application, or KMZ60,115 equivalent, this page provides verified technical context, validated pin functions, automotive-grade angular accuracy specs (±0.1° static inaccuracy), real-world ECU interface guidance, and confirmed alternatives for BLDC motor control and EPS systems.
Technical Context
The KMZ60,115 integrates two interleaved Wheatstone bridges (cosine/sine) on a single die, with MR sensing based on permalloy thin-film technology. Its signal chain includes PTAT-based temperature compensation, supply-voltage-dependent current multipliers, and rail-to-rail output buffers delivering ratiometric signals referenced to VCC/2.
Pin TCC_EN enables or disables TC compensation of output amplitude; POWERDOWN_EN places VOUT1/VOUT2 in high-impedance state and disables VTEMP. The device implements broken bond wire detection, short-circuit protection (±6 mA), and meets AEC-Q100 Grade 0 (−40 °C to +150 °C ambient) with 4 kV HBM ESD rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - Enables direct interfacing with 3.3 V or 5 V ECUs without level-shifting. |
| Angular Inaccuracy (Static) | ±0.1° - Measured under homogeneous 25 kA/m field; enables high-precision rotor position feedback in BLDC commutation. |
| Operating Temperature | −40 °C to +150 °C - Fully automotive qualified for under-hood EPS and motor control applications. |
| Output Type | Single-ended ratiometric sine/cosine - Output voltages scale linearly with VCC, minimizing ADC input range errors when referenced to same supply. |
| Max Rotational Frequency | 25,000 r/min - Supports high-speed BLDC operation up to ~417 Hz electrical frequency. |
| Power-Down Current | ≤16 μA - Reduces system standby power in EPS or wiper modules during vehicle sleep modes. |
| TC Compensation Enable | Dedicated TCC_EN pin - Connect to VCC for amplitude TC compensation; connect to GND for uncompensated mode with higher sensitivity at low temperature. |
Pinout & Package
Package: SO8 (SOT96-1), plastic small outline, 8-lead, 3.9 mm body width - compatible with standard surface-mount assembly and automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TCC_EN | Temperature coefficient compensation enable | Logic-controlled switch: VCC enables TC compensation; GND disables it, exposing raw MR signal with negative TC. |
| 2 - VOUT1 | Cosine channel output | Ratiometric single-ended analog output (0.07–0.93×VCC); matched in amplitude/phase with VOUT2 for arctan calculation. |
| 3 - GND | Ground reference | Primary ground return for sensor bridge, amplifier, and output buffers; dual GND pins (3 & 6) reduce ground impedance. |
| 4 - VOUT2 | Sine channel output | Ratiometric single-ended analog output (0.07–0.93×VCC); phase-matched to VOUT1 within ±1.5° up to 25,000 r/min. |
| 5 - VTEMP | Temperature reference output | Ratiometric PTAT voltage (0.057–0.786×VCC over −40 °C to +150 °C); used for external temperature compensation or diagnostics. |
| 6 - GND | Ground reference | Second ground terminal - improves noise immunity and thermal stability in high-EMI automotive environments. |
| 7 - VCC | Supply voltage input | 2.7–5.5 V power input; requires 100 nF blocking capacitor placed close to pin per EMC requirements. |
| 8 - POWERDOWN_EN | Power-down mode enable | Active-high input: VCC forces VOUT1/VOUT2 into high-Z and disables VTEMP; must be tied to GND if unused. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated MR sensor + amplifier | Single SO8 package replaces discrete MR bridge + op-amp + reference circuit - reduces BOM count and layout area by >50%. |
| Ratiometric sine/cosine outputs | VOUT1/VOUT2 track VCC proportionally - eliminates supply-voltage-induced angle error when paired with VCC-referenced ADCs. |
| Programmable TC compensation | TCC_EN pin selects between compensated (±0.1° static error over temp) or uncompensated (higher dynamic range at low temp) operation. |
| Built-in fault detection | Broken bond wire detection pulls VOUT1/VOUT2 to GND on internal failure - enables fail-safe motor control shutdown. |
| Automotive EMC compliance | Meets IEC 62132-4 (12 dBm immunity) and IEC 61967-4 (Class III emission) - validated on VOUT1/VOUT2/VTEMP/VCC/POWERDOWN_EN pins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMS AS5055A-BQFT | 12-bit SPI digital output; no integrated amplifier; requires external excitation field control. | Targets space-constrained consumer drones and robotics where digital interface and lower power (<1.5 mA) are prioritized over analog simplicity. | Select AS5055A-BQFT only if digital output and minimal external components outweigh need for analog ratiometric compatibility with legacy ECU ADCs. |
| Infineon TLE5012B E1000 | 32-bit SENT/SSI output; integrated angle calculation; supports 360° absolute position without arctan processing. | Designed for next-gen xEV inverters requiring diagnostic-ready digital interfaces and ASIL-B functional safety compliance. | Choose TLE5012B E1000 when system-level safety certification (ISO 26262) and embedded angle computation are required - not for drop-in replacement. |
Compared with AMS AS5055A-BQFT and Infineon TLE5012B E1000, the KMZ60,115 offers analog ratiometric outputs that directly interface with existing VCC-referenced ADCs in cost-sensitive automotive ECUs, eliminating firmware angle computation and reducing BOM complexity - making it optimal for high-volume BLDC and EPS designs where analog signal integrity and temperature-stable linearity are critical.

FAQ
What is the primary sensing principle used in the KMZ60,115?
The KMZ60,115 employs magnetoresistive (MR) sensing using two interleaved Wheatstone bridges fabricated in permalloy thin film. It detects the direction of a rotating magnetic field parallel to the chip surface, generating cosine and sine output signals proportional to the mechanical angle α, with output functions cos(2α) and sin(2α).
How does the KMZ60,115 achieve temperature compensation of its output amplitude?
The KMZ60,115 achieves temperature compensation via the TCC_EN pin: when connected to VCC, internal circuitry uses PTAT current sources and supply buffering to counteract the negative temperature coefficient of the MR bridge, reducing amplitude drift to ±0.1° static angular inaccuracy over −40 °C to +150 °C.
Can the KMZ60,115 be used with a 3.3 V microcontroller ADC?
Yes - the KMZ60,115's ratiometric outputs (VOUT1/VOUT2 = 0.07–0.93×VCC) scale directly with its 2.7–5.5 V supply. When powered from 3.3 V, its outputs span ~0.23–3.07 V, matching typical 3.3 V-referenced ADC input ranges without external scaling or level-shifting circuitry.
What happens to the outputs during power-down mode on the KMZ60,115?
When POWERDOWN_EN is driven high, the KMZ60,115 places VOUT1 and VOUT2 into high-impedance state (≥500 kΩ), disables the VTEMP output, and reduces supply current to ≤16 μA. This preserves system power while allowing fast wake-up (<110 μs) upon re-enabling the device.
Is the KMZ60,115 qualified for automotive applications?
Yes - the KMZ60,115 is fully AEC-Q100 qualified (Grade 0, −40 °C to +150 °C ambient), RoHS compliant, halogen- and antimony-free (Dark Green), and validated for EMC immunity (IEC 62132-4) and emission (IEC 61967-4), making it suitable for under-hood BLDC, EPS, and throttle applications.
