Semiconductors & interconnect

Parts you can still buy in ten years.

Microcontrollers, power management and interconnect with published lifecycle commitments, open datasheets and parametric selection — no login, no gate.

Request samples Start parametric search

Populated circuit board photographed close up: rows of surface-mount microcontrollers and passives on a green PCB.

Parametric selection

Filter first, read the datasheet second.

No login, no registration wall — narrow the catalogue to the handful of order codes that fit before you spend time reading anything.

Product families

Three families, one qualification record.

One audit covers all three families, so adding a second line to an existing design does not restart your supplier approval.

Macro photograph of a QFP microcontroller package with gull-wing leads. — OV-M4 series in LQFP-64 — the same die is offered in QFN-48 and WLCSP.

Microcontrollers11 series

Arm Cortex-M0+ to M33, 16 KB to 2 MB flash.

Macro photograph of a power module in a metal-tab package with thick copper leads. — OV-P6 synchronous buck in a metal-tab package — the tab is the thermal path.

Power management8 series

Buck, boost and LDO regulators to 6 A, plus gate drivers.

Macro photograph of a fine-pitch board-to-board connector pair with gold-plated contacts. — OV-C04 0.4 mm pitch pair, mated height 1.5 mm — gold over nickel contacts.

Interconnect6 series

Board-to-board and wire-to-board, 0.4 to 2.0 mm pitch.

Every order code, in HTML.

Specifications are readable on the page and indexable by search engines, not locked inside a PDF.

Tape-and-reel of surface-mount components on a workbench beside a ballpoint pen for size reference. — A 4000-piece reel next to a pen — the QFN-48 body is 7 × 7 mm, smaller than the pen clip.

Applications

Same silicon, four different approval regimes.

We issue the documentation each regime expects, so your quality team is not chasing us for a record halfway through a submission.

Semiconductor back-end assembly and test line with enclosed handlers and tape-and-reel spools. — Back-end assembly and test — the qualification record covers this line, not a family at a time.

Automotive

Grade 1 parts with PPAP and IMDS records for body, lighting and sensing nodes.

Industrial

Long-lifecycle parts for drives, metering and factory sensing.

Energy

Isolated gate drivers and MCUs for inverters, chargers and BMS.

Medical

Documented change control for devices under design-history-file discipline.

Quality & reliability

Certificates with numbers on them.

Every number below is publicly checkable, so your compliance reviewer can verify us without opening a ticket with our sales team.

Quality certifications with numbers and scope
Standard	Issuing body	Number	Scope
IATF 16949:2016	DEKRA	IATF-0421187	Wafer test and assembly sites
ISO 9001:2015	DEKRA	DK-9001-11842	All sites
AEC-Q100 Grade 1	Self-certified, report on request	AQ100-OV-2024-07	Automotive families
RoHS 3 / REACH SVHC	Declaration	DoC-2024-118	Full catalogue

Certificate numbers are specimen values for this demonstration — replace with the issued numbers before publication.

Reliability test laboratory with rows of environmental test chambers and burn-in racks. — Environmental chambers and burn-in racks — where the Grade 1 temperature claim is actually measured.

Hardware engineer's bench with a development board wired to an oscilloscope, a bench supply and a printed schematic. — What an evaluation actually looks like — the reference design, the printed schematic and a scope on the switching node.

What an engineer opens before the sample arrives.

Layout rules, reference designs and derating notes are published, so evaluation can start before the reel is on your desk.

AN-114Application noteLayout rules for the OV-P6 buck at 2 MHz — loop area, thermal vias, EMI.
RD-207Reference designThree-phase BLDC drive, OV-M4 plus OV-P6 rail, schematic and BOM.
SG-03Selection guideChoosing between QFN-48 and LQFP-64 for the same die.
AN-129Application noteMeeting AEC-Q100 Grade 1 derating in a 125 °C under-hood node.

Tell us the order code, or the problem.

If you already have a part number we will quote it. If you have a rail and a temperature range, an applications engineer will pick one.
