... PVCC This pin provides the bias supply for ISL8204M, ISL8206M, as well as the low-side MOSFET’s gate and high-side MOSFET’s gate. If PVCC rises above 6.5V, an internal 5V regulator will supply to the internal logics bias (but high-side and low-side MOSFET gate will still be sourced by PVCC). Connect a well decoupled +5V or +12V supply to this pin. Connect 1µ ...

If ISL8204M, ISL8206M is disabled after soft-start (by pulling COMP/EN pin low), and afterwards enabled (by releasing the COMP/EN pin), then the full initialization (including OCP sample) will take place. However, there is no new OCP sampling during overcurrent retries ...
