Figure 17. OVP with sink enabled: the low-side MOSFET is turned-on in advance
Figure 18. OVP with sink disabled: delay on the OVP operation
The L6730B can always sink current and so the OVP will operate always in advance. The
device realizes the over-current-protection (OCP) sensing the current both on the high-side
MOSFET(s) and the low-side MOSFET(s) and so 2 current limit thresholds can be set (see
OCH pin and OCL pin in
●
●
The peak current protection is active when the high-side MOSFET(s) is turned on, after an
adjustable masking time (see
enabled when the low-side MOSFET(s) is turned on after a fix masking time of about 400
ns. If, when the soft-start phase is completed, an over current event occurs during the on
time (peak-current-protection) or during the off time (valley-current-protection) the device
