HV310, Hotswap Controller, Negative Supply controls the power supply connection during insertion of cards or modules into live backplanes. It may be used in traditional ‘negative 48V’ powered systems or for higher voltage busses up to negative 90V.
Operation during the initial power up prevents turn-on glitches, and after complete charging of load capacitors (typically found in filters at the input of DC-DC converters) the HV310 issues a power good signal. This signal is typically used to enable the DC-DC converter. Once a PWRGD signal has been established, the device sleeps in a low power state, important for large systems with many individual hotswap cards or modules.
An external power MOSFET is required as the pass element, plus a ramp capacitor, and resistors to establish current limiting and over and under voltage lockouts. There is no need for additional external snubber components.
Features are programmable over voltage and under voltage detection of the input voltage which locks out the load connection if the bus (input) voltage is out of range. An internal voltage regulator creates a stable reference, and maintains accurate gate drive voltage. The unique control loop scheme provides full current control and limiting during start up.
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.
HV310 is an authentic electronic component manufactured by Microchip, categorized under Power Management ICs. 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 HV310 datasheet above.
Electronic component spot-market pricing for HV310 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 HV310 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.
