The EVQ3321-QQE-00A evaluation board is designed to demonstrate the capabilities of the MPQ3321-AEC1 and MPQ3321A-AEC1, 48-channel LED drivers with a 22V voltage rating and maximum 80mA current sources. It is designed to drive the LED arrays as local dimming backlighting in automotive LCD panels. The MPQ3321-AEC1 and MPQ3321A-AEC1 employ low headroom to regulate the LED current (ILEDx). The adaptive voltage feedback function optimizes the LED voltage, which achieves higher system efficiency. The MPQ3321-AEC1 and MPQ3321A-AEC1 support independent 16-bit pulse-width modulation (PWM) and 7-bit analog dimming for each channel via the serial interface. The configurable internal registers provide reliable and flexible application. The 25MHz serial interface clock guarantees a high data transfer rate for multiple devices operating in a daisy chain application. Robust protections are included to guarantee safe operation of the device. Protection modes include LED open protection, LED short protection, and over-temperature protection (OTP). All fault statuses can be read through the serial interface. The MPQ3321-AEC1 and MPQ3321A-AEC1 are available in QFN-68 (8mmx8mm) packages. They are available in AEC-Q100 Grade 0.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
EVQ3321-QQE-00A is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Development Tools. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official EVQ3321-QQE-00A datasheet above.
Electronic component spot-market pricing for EVQ3321-QQE-00A fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for EVQ3321-QQE-00A depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
