PL-0301

AC/DC Power Protection IC

OVERVIEW

The PL-0301 Power Protection IC is designed to provide overload protection for the AC/DC power system. It

can be used for power protection ranges from mA to KA depending on the current transformer specification.

Built-in internal three overload detection modes (short circuit, abnormal and overload) to check different

overload conditions. The short circuit overload detection can detect the short circuit condition under 500us. It

will cut off the power immediately to prevent the electrical device from burning out. For the abnormal

overload protection, the chip can monitor the abnormal current increase. If the current increases too fast and

will damage the electrical device, the PL-0301 chip will cut off the power. The overload protection works

when the current under normal condition is too large generating too much heat. The PL-0301 will depend on

the current condition to decide when to cut off the power and to prevent the electrical device from overheat.

PL-0301 also can support the AC/DC leakage detection/protection. Over/under voltage detection/protection

can be optional in the next advanced chip.
