Ps42419ha Schematic Top Patched

The PMU block manages the power distribution, monitoring, and control of the IC. The PMU includes features such as under-voltage lockout (UVLO), over-voltage protection (OVP), and current limiting.

Without these components, the high-side switches will not turn on. The schematic top often uses dashed lines to indicate that these capacitors must be supplied externally. ps42419ha schematic top
