High Voltage Input Protection Device
The ADM1270 is designed to control the inrush current, when powering on the system, via an external P-channel field effect transistor (FET).
To protect the system from a reverse polarity input supply, there is a provision made to control an additional external P-channel FET. This feature prevents reverse current flow in case of a reverse polarity connection, which can damage the load or the ADM1270.
The ADM1270 is available in a 3 mm × 3 mm, 16-lead LFCSP and a 16-lead QSOP.
