It combines three separate chips—a p-channel high-side MOSFET, an n-channel low-side MOSFET, and a dedicated driver IC—into a single compact package, delivering a complete power stage solution for brushed DC motors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExceptional Current Handling Capability\u003c\/strong\u003e\u003cbr\u003eThe BTN7930B supports continuous output currents of up to 32A, making it ideal for demanding automotive loads such as engine cooling fans, HVAC blowers, fuel pumps, and power window motors. The typical path resistance is only 28mΩ at room temperature, with maximum values of 17mΩ for the high-side and 38mΩ for the low-side at 150°C, ensuring efficient power delivery with minimal thermal losses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSimplified Control and Low EMI\u003c\/strong\u003e\u003cbr\u003eInterfacing with a microcontroller is straightforward thanks to logic-level inputs that eliminate the need for complex gate drive circuitry. The p-channel high-side MOSFET removes the requirement for a charge pump, significantly reducing electromagnetic interference (EMI) and simplifying system design. The device supports PWM frequencies up to 25kHz with active freewheeling for precise speed and torque control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComprehensive Protection and Diagnostics\u003c\/strong\u003e\u003cbr\u003eDesigned for harsh automotive environments, the BTN7930B integrates a full suite of protection features including overtemperature shutdown with latch behavior, overvoltage lockout, undervoltage shutdown, and overcurrent protection. The current limitation level is set at 20A minimum and 32A typical. A status flag diagnosis with current sense capability provides real-time feedback to the system microcontroller, allowing for intelligent fault management and system monitoring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWide Operating Range and Automotive Qualification\u003c\/strong\u003e\u003cbr\u003eOperating from an 8V to 18V supply voltage and qualified for the full automotive temperature range of -40°C to +150°C, the BTN7930B delivers reliable performance under extreme under-hood conditions. Its low quiescent current of typically 7μA contributes to overall system efficiency in modern vehicles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVersatile Configuration and Surface-Mount Package\u003c\/strong\u003e\u003cbr\u003eThe BTN7930B can be combined with other identical devices to form H-bridge and 3-phase drive configurations, offering scalability for various motor control topologies. Housed in a surface-mount PG-TO263-7 package, it is RoHS-compliant and supports automated PCB assembly.\u003c\/p\u003e","brand":"Qlnova","offers":[{"title":"Default Title","offer_id":45456238444653,"sku":null,"price":4.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5950\/8845\/files\/BTN7930B-1.webp?v=1784013517","url":"https:\/\/qlnova.com\/products\/btn7930b-high-current-half-bridge-motor-driver-32a-automotive-dc-motor-controller-ic","provider":"Qlnova","version":"1.0","type":"link"}
