This device is engineered to operate under extreme environmental conditions, making it an ideal solution for engine management systems and electronic throttle control (ETC) modules.\u003c\/p\u003e\n\u003cp\u003eThis robust driver operates with a supply voltage range from 5V to 28V, providing flexibility for various automotive electrical architectures. It delivers a continuous DC load current of 5A (at Tcase \u0026lt; 100°C) with a typical RDS(on) of just 150 mΩ per output transistor at 25°C, ensuring efficient power delivery and reduced heat generation.\u003c\/p\u003e\n\u003cp\u003eThe device features comprehensive protection mechanisms essential for automotive reliability. Output current limitation is triggered at a typical 8.6A, while short-circuit shutdown activates for output currents exceeding 10.6A, safeguarding both the driver and connected actuators from fault conditions. Over-temperature protection and undervoltage disable function provide additional layers of system security.\u003c\/p\u003e\n\u003cp\u003eDiagnostic capabilities are configurable via SPI or a dedicated status-flag output, offering flexibility for different system architectures. The logic inputs are TTL\/CMOS-compatible, and the device supports operating frequencies up to 30kHz, enabling precise motor control in demanding applications.\u003c\/p\u003e\n\u003cp\u003eThe L9929 has been widely adopted in automotive ECU designs, including engine control modules and electronic throttle control systems, where precise and reliable motor actuation is critical. Housed in a SO20 power package, this IC delivers the performance, protection, and diagnostic features required for next-generation powertrain and chassis control applications.\u003c\/p\u003e","brand":"Qlnova","offers":[{"title":"Default Title","offer_id":45422264287341,"sku":null,"price":2.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5950\/8845\/files\/L9929-3.webp?v=1783047841","url":"https:\/\/qlnova.com\/products\/l9929-spi-controlled-h-bridge-driver-ic-5a-continuous-output-for-engine-ecu-electronic-throttle-control-systems","provider":"Qlnova","version":"1.0","type":"link"}
