FieldCurrent / extracted valueReview
MPNJY01Matches datasheet/product page.
Manufacturer NameCrossicMismatch/unclear: datasheet/product page indicate Shanghai JUYI Tech / Shanghai Juyi Electronic Technology Development Co., Ltd. Crossic appears more likely to be a catalog/source than the silicon manufacturer.
Part TypeIntegrated CircuitsAcceptable; more specific category would be BLDC motor controller IC.
Designator PrefixICOK.
Pin count16Matches datasheet SOP16 pin table.
PackageSOP16 in datasheet; current footprint SOIC127P600X175-16N.kicad_modPlausible for SOP16, but exact manufacturer mechanical dimensions were not extractable from OCR. Treat as compatible unless a package drawing shows a different SOP16 variant.
DescriptionJY01 brushless DC motor controller ICMatches datasheet.
3D modelJY01.stpPresent; not dimension-verified in this review.

SpecDatasheet value
FunctionIntegrated 2-in-1 Hall/sensorless BLDC motor controller IC
Supply / working voltage4.5 V to 5.5 V, typical 5 V
Operating temperature-40 °C to +85 °C
Drive modeSPWM
Motor supportHall-sensor BLDC or sensorless BLDC
Speed controlLinear speed control via VR, 0 V to 2.5 V or 0 V to 5.0 V
Direction controlZ/F pin, connect to Vss or Vdd for CW/CCW
Output polarityPositive-polarity drive outputs; MOS drive circuit must account for this
Overload thresholdIS pin approximately 0.1 V starts overload/constant-current behavior
Protection thresholdIS pin approximately 0.2 V triggers protection, extracted timing about 4.5 us
Current-sense formulaI = 0.1 / R, where R is the current-sense resistor in ohms
Blocking protectionStops output if motor does not start normally; extracted text says about 3 s, while some revision text references 2.5 s
Soft-start options1 s, 3 s, or 10 s optional

Symbol review
  • The symbol has 16 terminal entries and the pin-number ordering matches the datasheet for pins 2 through 16.
  • Pin 1 is the main symbol mismatch: current terminal name FO/EL does not match the datasheet Brak / brake-control multifunction pin.
  • All terminal Pin Type properties are currently Unspecified; datasheet-supported pin types should be added for ERC quality.
  • No detailed Pin Description properties are currently present on the terminal entries; adding datasheet descriptions would improve part quality.
Footprint review
  • Current footprint asset: SOIC127P600X175-16N.kicad_mod.
  • Inline footprint has 16 SMD pads, 1.27 mm pitch, pads approximately 0.65 mm x 1.525 mm, and a nominal SOIC/SOP-16 outline.
  • Datasheet/product page specify SOP16 packaging, so this footprint is plausible.
  • The available OCR did not expose a numeric manufacturer mechanical drawing; final approval should compare against the original package drawing if available.
Mismatches / action items
  1. Rename or justify pin 1: current FO/EL vs datasheet Brak / brake-control multifunction pin.
  2. Consider changing Manufacturer Name from Crossic to Shanghai JUYI Tech or Shanghai Juyi Electronic Technology Development Co., Ltd., unless Crossic is intentionally used as supplier/source.
  3. Add terminal Pin Description metadata for all 16 pins from the datasheet.
  4. Assign terminal Pin Type metadata: power, ground, input, output, analog input, and drive-output as appropriate.
  5. Mechanically confirm the SOP16 package drawing if manufacturing risk is high; the existing SOIC/SOP-16 footprint is plausible but not proven by extracted dimensions.
