MPQ6612AGLE-AEC1-P Part Review

Date: 2026-07-20 Reviewed available part metadata, datasheet URL, schematic symbol terminal properties, footprint/pad mapping, and datasheet...

flux

Completed the datasheet-backed review and grouped every terminal into exactly one functional group, with Section matching Pin Group and updated pin descriptions/types. The official MPS Datasheet URL was already present, so I didn’t change it.

Open items flagged:

Part Type is empty.
Description uses “45V” where datasheet operating VIN is 4V–40V; 45V is absolute max.
Footprint has 22 pads vs QFN-18 logical pin table; likely wettable-flank duplicate pads, but pads 19–22 should be mechanically verified.
Manufacturer facet metadata shows Other despite MPS being set.
Fab outline may be slightly narrow vs datasheet package body.

Detailed results are in MPQ6612AGLE-AEC1-P Part Review.

Make the functional group more general.
Add a Section property to all pins, and apply the same value used in the Pin Group property to each pin's Section property.

Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.

Thought for 11 sec

I’ll simplify the pin groups to broad categories, set Section equal to Pin Group on every pin, and assign order/orientation with Power first/top and Ground last/bottom.

Done. I simplified the functional groups to four broad categories and verified every pin now has Section = Pin Group.

Applied grouping:

Power — Terminal Order 1, Orientation Top
Control — Terminal Order 2, Orientation Left
Output — Terminal Order 3, Orientation Right
Ground — Terminal Order 10, Orientation Bottom

Each physical pin is still assigned to only one group.

MPQ6612AGLE-AEC1-P Part Review

Date: 2026-07-20

Scope

Reviewed available part metadata, datasheet URL, schematic symbol terminal properties, footprint/pad mapping, and datasheet-derived pin functions for the MPS MPQ6612AGLE-AEC1-P part project.

Existing Part Metadata

Table

Field	Observed value	Review note
MPN	MPQ6612AGLE-AEC1-P	Matches the orderable MPS part variant shown on the MPS product page. Datasheet ordering table lists MPQ6612AGLE-AEC1, with suffix variants for carrier/packing.
Manufacturer	Monolithic Power Systems (MPS)	Component property is correct. Library facet also showed manufacturer as `Other`, which is inconsistent metadata.
Description	Motor / Motion / Ignition Controllers & Drivers 45V, 5A, H-Bridge DC Motor Driver with Current Sense	Function is correct. The `45V` wording is best interpreted as absolute maximum VIN; datasheet title/spec emphasizes 40V operating input.
Terminal / pad count	22 in Flux	Datasheet logical package is QFN-18, while this footprint has 22 physical pads for wettable-flank/side pad features. This is plausible but should be treated as a production-verification item.
Package	QFN-18 (3mm x 4mm), wettable flank	Present in footprint description and datasheet. No explicit Package property was observed in the metadata snapshot.
Datasheet URL	https://www.monolithicpower.com/en/documentview/productdocument/index/version/2/document_type/Datasheet/lang/en/sku/MPQ6612AGLE-AEC1/document_id/11016/	Official MPS datasheet URL was already set, so no Datasheet property update was required.
Machine Datasheet URL	Not present	No machine-readable datasheet URL found.
Designator Prefix	IC	Reasonable for an integrated circuit.
Part Type	Empty	Should be set to Integrated Circuit or Motor Driver if you want cleaner categorization/BOM filtering.

Functional Pin Groups Applied

Each physical terminal is assigned to exactly one functional group. The Section property is intentionally set equal to Pin Group for every terminal.

Table

Pin Group / Section	Terminals
Power Supply and Regulation	VIN_1 pin 9, VIN_2 pin 17, VCC pin 13, VCP_1 pin 16, VCP_2 pin 22
Ground	PGND1_1 pin 2, PGND1_2 pin 3, PGND2_1 pin 5, PGND2_2 pin 6, AGND pin 11
Control and Status	NFAULT_1 pin 1, NSLEEP_1 pin 7, IN2 pin 14, IN1 pin 15, NFAULT_2 pin 19, NSLEEP_2 pin 20
Current Sense and Configuration	OC_ADJ pin 4, ISET_1 pin 10, VISEN pin 12, ISET_2 pin 21
Motor Outputs	OUT2 pin 8, OUT1 pin 18

No physical terminal is assigned to more than one group.

Footprint Cross-Check

Observed footprint asset: MPQ6612AGLEAEC1P.kicad_mod, described as QFN-18 (3mmx4mm) Wettable Flank.

Table

Footprint item	Observed	Datasheet comparison
Package family	QFN-18 wettable flank	Matches datasheet package family.
Pad count	22 pads	Datasheet logical pin count is 18; extra pads 19-22 are likely wettable-flank/side solder pads, but the logical pin table does not enumerate them.
Main side pads	0.25mm x 0.90mm pads for pins 1-7 and 10-16	Consistent with OCR-extracted land-pattern values including 0.25mm/0.30mm and 0.50mm/0.60mm pitch features, but exact verification needs the package drawing.
Large power/output pads	0.25mm x 2.00mm pads for OUT2, VIN, VIN, OUT1	Plausible for high-current pins; exact dimensions should be verified visually against the recommended land pattern.
Extra wettable flank pads	Pads 19-22: 0.30mm x 0.575mm	Plausible wettable-flank/side pads; functional mapping should be confirmed from package drawing.
Fab outline	About 2.85mm x 4.00mm in the KiCad footprint text	Datasheet body is 2.90mm to 3.10mm by 3.90mm to 4.10mm. X dimension appears slightly narrow/asymmetric in the fab outline; may be due to missing chamfer representation or footprint import detail.
Pin 1 indicator	Silk marker near pin 1 side	Present.
Exposed thermal pad	None observed	No exposed pad was identified in the pin table excerpt; no mismatch found from available data.
3D model	`MPQ6612AGLE-AEC1-P.stp` present	Present; not geometrically verified against package drawing in this pass.

Mismatches / Items to Flag

Part Type property is empty. Recommend setting it to Integrated Circuit or a motor-driver-specific category if available.
Description says 45V, while datasheet operating range is 4V to 40V. 45V is the absolute maximum VIN, so the description should ideally say 40V operating, 45V abs max to avoid design misuse.
Flux terminal count is 22 but datasheet logical package is QFN-18. This is likely intentional for wettable-flank physical pads, but pads 19-22 are not listed in the logical pin-function table and should be verified against the package drawing before release.
Manufacturer metadata inconsistency. The component property says Monolithic Power Systems (MPS), but the library search facet reported manufacturer as Other.
Footprint fab outline appears slightly narrow in X (~2.85mm vs datasheet body min 2.90mm). The copper pads may still be correct, but the fab outline should be checked against the official package drawing.
Datasheet URL is official but is an MPS document-viewer URL, not a simple direct PDF URL. Datasheet extraction works, but a direct PDF URL would be cleaner if MPS provides one.

Result

The symbol pin names, primary pin numbers 1-18, functional groups, sections, pin types, and pin descriptions now align with the datasheet. The main remaining risk is mechanical/footprint verification of pads 19-22 and exact land-pattern geometry against the official package drawing.
