{"product_id":"mc33926-throttle-control-ignition-driver-ic","title":"MC33926 – Throttle Control \u0026 Ignition Driver IC for Automotive ECU Board, Common Replacement Part","description":"\u003cp\u003eThe MC33926 is a monolithic H-bridge power IC designed for automotive engine control units. It is widely used for electronic throttle control (ETC) and can also serve as an ignition coil or DC motor driver.\u003c\/p\u003e\n\u003cp\u003eThis chip is a known common failure component on many vehicle computer boards. Symptoms of a failed MC33926 include unresponsive throttle, limp mode, reduced engine power, or ignition-related fault codes. Direct replacement of this vulnerable IC can restore normal throttle and ignition functions without replacing the entire ECU.\u003c\/p\u003e\n\u003cp\u003eKey technical features:\u003c\/p\u003e\n\u003cp\u003e    Integrated H-bridge with low RDS(on) MOSFETs for high efficiency\u003c\/p\u003e\n\u003cp\u003e    Operating voltage range 5V to 28V, suitable for automotive 12V systems\u003c\/p\u003e\n\u003cp\u003e    Built-in overcurrent, overtemperature, and short-circuit protection\u003c\/p\u003e\n\u003cp\u003e    PWM control capability up to 20kHz for precise throttle positioning\u003c\/p\u003e\n\u003cp\u003eTypical applications: electronic throttle control modules, aftermarket ECU repairs, idle air control valves, and automotive computer board rebuilding.\u003c\/p\u003e\n\u003cp\u003eDuring replacement, use proper hot air rework equipment and follow ESD-safe procedures. Verify board layout and pin compatibility before soldering. This IC solves common throttle and ignition drive failures in a cost-effective and reliable manner.\u003c\/p\u003e","brand":"Qlnova","offers":[{"title":"Default Title","offer_id":45218223587437,"sku":null,"price":8.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5950\/8845\/files\/3_3be5afbe-0969-47e4-86f9-d661e40acf2f.webp?v=1779347662","url":"https:\/\/qlnova.com\/products\/mc33926-throttle-control-ignition-driver-ic","provider":"Qlnova","version":"1.0","type":"link"}
