MT6816CT-ACD-R

Magn Tek · Position Sensor · SOP-8

MT6816CT-ACD-R from Magn Tek, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CSN input SPI chip-select / enable input (active low). Has an internal pull-up (leakage spec references CSN internal pull-up). Digital input logic thresholds referenced to VDD (VIH ≥ 0.7VDD, VIL ≤ 0.3VDD).
2 HVPP power_in Dual-function pin. Accepts ~7.0-7.2 V during MTP (NVM) programming, and selects SPI vs. ABZ/UVW output mode during normal operation: tie to VDD for SPI mode, tie to GND for ABZ or UVW mode. Absolute max 8 V.
3 OUT output PWM angle-output pin. Push-pull digital output; PWM frequency is programmable, default 971.1 Hz (±8%), 12-bit absolute angle encoded as duty cycle. Max source/sink 20 mA.
4 VDD power_in Main supply pin, 3.3-5.0 V typical (3.0-5.5 V operating range, 6.5 V absolute max). Feeds an internal LDO that powers the AMR bridges and digital core. Typical Idd = 10 mA, max 15 mA.
5 A/U/MOSI/SDAT bidirectional Muxed I/O. Functions: incremental encoder A output (ABZ mode), commutation U output (UVW mode), SPI MOSI (4-wire SPI), or SDAT bidirectional data (3-wire SPI). Push-pull, ±20 mA max.
6 B/V/MISO bidirectional Muxed I/O. Functions: incremental encoder B output (ABZ mode), commutation V output (UVW mode), or SPI MISO (4-wire SPI). Unused in 3-wire SPI. Push-pull, ±20 mA max.
7 Z/W/SCK bidirectional Muxed I/O. Functions: incremental encoder Z index output (ABZ mode), commutation W output (UVW mode), or SPI clock input (3-wire or 4-wire SPI). Push-pull, ±20 mA max.
8 GND power_in Device ground / substrate return.

CAD (KiCad official)

  • Symbol: MT6816CT-ACD-R
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: mt6816ct-acd-r-etched.step / mt6816ct-acd-r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mt6816ct-acd-r.step / mt6816ct-acd-r.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mt6816ct-acd-r.step 122 KB You want the bare part, or you mark your own boards.
mt6816ct-acd-r-etched.step 2.5 MB You want the part with MT6816CT-ACD-R already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 608 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Magn Tek datasheet (30 pp, sha256 74b66b99a0d6b0e4, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
