Product Details

The EVAL-ADM1073MEBZ is a compact, full feature evaluation board for the ADM1073 device. The layout provides users with a clear visual of all the peripheral components and the hot swap power path. The layout also maximizes the ability of the board to dissipate heat for some of the key components on the power path, allowing evaluation of high current hot swap setups.

One sense resistor footprint and one FET footprint provides users with flexibility and allows them to simulate a wide range of application setups.

Multiple test points allow easy access to all critical points and pins. There is one LED to provide users with a direct visual indication of IC power good output.

This evaluation kit allows the ADM1073 negative-voltage hot swap controller to be easily evaluated. The ADM1073 provides undervoltage and overvoltage protection by monitoring the supply voltage and provides robust current limiting by monitoring the load current. The device uses an FET in the power path to control the load current.

Complete specifications for the ADM1073 can be found in the ADM1073 data sheet, available at www.analog.com, and should be consulted in conjunction with this user guide when using the evaluation board.
