HV738 is a four-channel, monolithic, high voltage, high speed pulse generator. It is designed for portable medical ultrasound applications. This high voltage and high speed integrated circuit can also be used for piezoelectric, capacitive or MEMS sensing in ultrasonic nondestructive detection and sonar ranger applications. The HV738 consists of a controller logic interface circuit, level translators, MOSFET gate drivers and high power P-channel and N-channel MOSFETs as the output stage for each channel. The output stages of each channel are designed to provide peak output currents over ±1.1A for pulsing, when in mode 4, with up to ±65 volt swings. When in mode 1, all the output stages drop the peak current to ±140mA for low-voltage CW mode operation to decrease the power consumption of the IC. The P and N type of power FETs gate drivers are supplied by two floating 8.0VDC power supplies referenced to VPP and VNN. This direct coupling topology of the gate drivers not only eliminates two high voltage capacitors per channel, but also makes the PCB layout easier.
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.
HV738 is an authentic electronic component manufactured by Microchip, categorized under Unclassified. 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 HV738 datasheet above.
Electronic component spot-market pricing for HV738 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 HV738 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.
