MMC5633NJL

MMC5633NJL is a MEMS-based magnetic rotary position sensor (angle sensor). It determines absolute angular position by measuring the magnetic field with an on-chip Hall sensor/dense sensor array and processing it with integrated electronics. The device provides a continuous 0–360° angle output and is designed for compact, low-power applications.
Key points:
- Output: absolute angle data (often via a serial digital interface such as SPI/I2C-compatible, plus status/error flags).
- Interface and features: digital readout, internal calibration and temperature compensation, programmable options, and low-power operation.
- Package: small footprint, suitable for integration into compact assemblies.
- Magnet/pole requirements: requires a magnet with an appropriate pole arrangement and alignment relative to the IC, per the datasheet.
Common applications:
- Brushless DC motor commutation, servo and robotics, automotive and industrial position sensing.
For specifics (supply voltage, temperature range, magnet geometry, register map, and programming), consult the MMC5633NJL datasheet and evaluation boards.

Key features of MMC5633NJL:
- 3-axis digital magnetometer (MEMS) for Earth’s magnetic field.
- Digital interfaces: I2C and SPI (configurable data formats).
- Programmable full-scale ranges per axis and selectable data rate.
- On-chip temperature sensor with temperature compensation.
- Built-in self-test and factory calibration; user-offset calibration available.
- Low-noise, high stability with good bias performance.
- Low-power operation with multiple modes (normal and sleep/power-down).
- Wide supply voltage and extended operating temperature range (typical MCU-friendly voltages; wide -40°C to +125°C class).
- Small package suitable for compact designs (e.g., surface-mup/molded QFN-like).
- Interrupt/data-ready signaling support for efficient data handling.
Note: For exact voltage, temperature, current, and range specs, refer to the datasheet.

MMC5633NJL uses a leadless, land-grid array (LGA) surface-mount package (no leads).
