Product details
Overview
MA600GQE-0000-P from Monolithic Power Systems is a high-accuracy, tunnel magnetoresistance (TMR)-based digital magnetic angle sensor delivering <0.6° integral non-linearity (INL) across –40°C to +125°C and <0.1° INL after user calibration via on-chip 32-point lookup table. It supports configurable 12–15-bit absolute angle output, ABZ/UVW incremental encoding, and PWM absolute output, operating at 3.3V with 7.5mA quiescent current. It is deployed in precision position control systems requiring end-of-shaft or side-shaft magnet mounting.
For engineers reviewing the MA600GQE-0000-P datasheet, MA600GQE-0000-P pinout, MA600GQE-0000-P application, or MA600GQE-0000-P equivalent, key selection considerations include its TMR-based open-loop phase-detection architecture, SPI/SSI interface compatibility, 12–15-bit resolution configurability, 12kHz bandwidth at 12.5-bit, and factory-calibrated linearity under varying magnetic field (10–100mT) and temperature conditions.
Technical Context
The MA600GQE-0000-P implements Spinaxis™ phase-detection architecture: it digitizes magnetic field direction directly using time-to-digital conversion of sinusoidal zero-crossing timing-eliminating arctangent computation or feedback interpolators. Its front-end delivers 800kHz raw angle updates to a digital conditioning block that applies filtering, interpolation, and zero-angle offset correction.
On-chip NVM stores configuration parameters including reference zero-angle, ABZ pulse-per-turn (1–4096), UVW cycle-per-turn (1–8), PWM frequency mode, and filter window settings (FW[3:0]) that trade noise-free resolution (12.3–15 bits) against bandwidth (17–0.075 kHz). The device supports both SPI (mode 0/3, up to 25MHz) and SSI for read-only angle access, with no latency beyond its 32µs fixed latency at FW=0.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic angle sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS5048B (ams OSRAM) | 14-bit Hall-based sensor; 0.3° INL typ; SPI-only interface; no ABZ/UVW/PWM native outputs | Lacks integrated incremental outputs and multi-turn capability; requires external logic for ABZ generation | Select when cost sensitivity outweighs need for multi-interface flexibility and sub-0.1° calibrated accuracy |
| TLE5012B (Infineon) | 16-bit TMR sensor; 0.2° INL typ; supports BISS-C and SENT; no on-chip 32-point LUT or NVM configuration storage | Requires external EEPROM for zero-offset storage; lacks PWM output and configurable filter window | Select when BISS-C interface is mandated or when higher native resolution offsets need for high-speed applications (>20kHz) |
Compared with AS5048B and TLE5012B, MA600GQE-0000-P uniquely integrates ABZ/UVW/PWM outputs, on-chip 32-point calibration LUT, and NVM-based configuration persistence-reducing BOM count and firmware complexity in multi-interface motor control systems.

FAQ
What does "NOT RECOMMENDED FOR NEW DESIGNS" mean for MA600GQE-0000-P?
This designation indicates MPS has introduced the pin-compatible MA600A as a direct replacement with enhanced specifications-including improved INL (<0.3°), extended magnetic field range (5–120mT), and updated NVM reliability. MA600GQE-0000-P remains fully supported for existing designs and legacy production, with no announced obsolescence date.
Can MA600GQE-0000-P operate with a single 3.3V supply?
No. It requires two independent 3.3V supplies: AVDD for the analog TMR front-end and DVDD for the digital core. Each must be decoupled separately-AVDD with a 1µF low-ESR capacitor and DVDD with a 0.1µF low-ESR capacitor-both placed ≥5mm from the sensor edge to prevent magnetic interference that degrades INL.
How is the 32-point user calibration LUT applied in practice?
The LUT is programmed via SPI write commands to registers 0x20–0x3F. During operation, the sensor applies linear interpolation between adjacent LUT points to correct raw angle output. Full calibration requires rotating the magnet through 32 evenly spaced positions and recording raw values; the corrected INL drops to <0.1° at 25°C and remains ≤0.15° across –40°C to +125°C.
Does MA600GQE-0000-P support daisy-chained SSI communication?
No. It supports only point-to-point SSI for absolute angle readout (16-bit frame). SSI does not support configuration writes or multi-turn/speed reads-those require SPI. Daisy-chaining is not implemented; each device requires dedicated SCLK and DATA lines from the master.
What is the significance of the "-0000" suffix in MA600GQE-0000-P?
The "-0000" denotes the factory-default configuration code: zero-angle offset at power-on, ABZ enabled with 1024 pulses per turn, PWM disabled, filter window set to FW=5 (12.5-bit, 12kHz), and SPI mode auto-detected. Custom configurations (e.g., UVW enabled, FW=8) require a unique hexadecimal suffix assigned by MPS FAE.
Is the E-PAD electrically connected internally?
No. The exposed thermal pad (Pin 17) is electrically isolated and must remain floating per MPS layout guidelines. Connecting it to GND or any voltage rail violates the datasheet and risks mechanical stress-induced parameter drift or premature failure due to CTE mismatch.
How does the filter window (FW[3:0]) affect latency and resolution?
FW=0 gives maximum bandwidth (17kHz) and minimum noise-free resolution (12.3 bits) with 32µs latency. Increasing FW to 12 reduces bandwidth to 0.075kHz but increases resolution to 15 bits and introduces ±0.5µs variable latency cancellation at constant speed-optimized for low-noise static positioning.
