... URRENT ROTECTION There are two separate current limit circuits in the LX1676. One looks at the phase 1 lower MOSFET drain current and the second looks at the phase 3 upper MOSFET drain current. Both circuits have a 400 nS delay before a current limit command is issued to the current limit latch, once set the current limit latch will hold all three phases off until it is reset ...
