The AAT4712 is an integrated P-channel MOSFET load switch with adjustable current limits, integrated discharge path, over temperature protection, a power loop and a super capacitor charger. The input current limit control is combined with an over-temperature thermal limit and power loop circuit to provide a comprehensive system to protect the load switch and its supply from load conditions exceeding the supply specifications.
A brief “Getting Started” section is included to help the user to begin operating the evaluation board. The AAT4712 evaluation board is shown in Figure 1; Figures 2 and 8 depict the board schematic and layout. For additional information, please consult the AAT4712 product datasheet.
