This device combines a full H-bridge power stage with comprehensive supervision and diagnostic functions in a compact 24-pin HSSOP package with an exposed thermal pad for efficient heat dissipation .\u003c\/p\u003e\n\u003cp\u003eThis driver operates across a wide battery supply voltage range from 5V to 28V, making it suitable for various automotive electrical architectures . It delivers a continuous load current exceeding 3A, with a full path RDS(ON) of less than 540 mΩ to ensure efficient power delivery . The output switching frequency supports up to 11 kHz, enabling precise PWM control for motor speed and torque regulation .\u003c\/p\u003e\n\u003cp\u003eThe device features flexible control interfaces, allowing the power stages to be configured either via a standard SPI interface or through two dedicated input signals (PWM and DIR), with SPI programmability for configuration . Comprehensive diagnostic capabilities include over-temperature protection, short-circuit protection, and full diagnosis reporting through the SPI interface . An error history register stores fault events for system-level analysis .\u003c\/p\u003e\n\u003cp\u003eAdditional safety features include VDD supply voltage monitoring, two independent enable pins (\/ABE and DIS) for fail-safe control, and a current-monitoring feedback output signal (CF) that provides real-time load current information . The device is logic-level 5V compatible and conforms to improved EMC requirements through smart H-Bridge switching techniques .\u003c\/p\u003e\n\u003cp\u003eThe L9959S-D is qualified for automotive applications and is ideally suited for throttle control actuators, exhaust gas recirculation (EGR) control valves, and other DC motor control applications in modern engine management systems .\u003c\/p\u003e","brand":"Qlnova","offers":[{"title":"Default Title","offer_id":45422264877165,"sku":null,"price":2.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5950\/8845\/files\/L9959S-D-3.webp?v=1783047948","url":"https:\/\/qlnova.com\/products\/l9959s-d-high-side-h-bridge-driver-ic-3a-continuous-output-with-spi-diagnosis-for-engine-throttle-control","provider":"Qlnova","version":"1.0","type":"link"}
