Description
Feature:
Using a complete two half-bridge driver chip + N-channel MOSFET with very low internal resistance, MOSFET switching losses to a minimum, to improve power efficiency than integrated power chip program power margin large.
Tip: The motherboard comes with 5V power supply signal source (such as SCM) to use, but can only provide 10-20MA current can not be overloaded.
