Low-Side-Less startup
In order to avoid any kind of negative undershoot on the load side during start-up, L6714
performs a special sequence in enabling LS driver to switch: during the soft-start phase, the
LS driver results disabled (LS=OFF) until the HS starts to switch. This avoid the dangerous
negative spike on the output voltage that can happen if starting over a pre-biased output
(See Figure
This particular feature of the device masks the LS turn-on only from the control loop point of
view: protections are still allowed to turn-ON the LS MOSFET in case of over voltage if
needed.
