Analog Devices Inc. EVAL-ADM1281-AZ Evaluation Board
Analog Devices Inc. EVAL-ADM1281-AZ Evaluation Board is a compact, full-featured evaluation board for the ADM1281 Hot-Swap Controller. The board layout provides a clear visual of all the peripheral components and the hot-swap power path. The layout also maximizes the board's ability to dissipate heat for some of the key components on the power path, which allows the evaluation of very high-current hot-swap setups. Five sense-resistor slots and six multipackage FET slots provide great flexibility and allow a wide range of application setups.
Multiple test points allow easy access to all critical points/pins. Seven LEDs provide a direct visual indication of variations in the board status, such as supply input, output, IC power-good output, fault output, current sense output, and general-purpose outputs (GPO). An AD7291 8-channel, I2C, 12-bit, successive approximation analog-to-digital converter (SAR ADC) allows users to measure voltages such as CSOUT and other pin voltages and read ambient board temperature through an I2C bus in real time.
The evaluation board supports I2C communication, allowing users to communicate with the ADM1281. The evaluation board also supports cascade setup so multiple evaluation boards can be connected and share the same I2C bus. The board is fully compatible with the Analog Devices hot-swap and power monitoring evaluation software (zip) and the LTpowerPlay tools. Users need a USB-SDP-CABLEZ or a DC1613A USB-to-I2C serial interface to use the evaluation software tools. The standard evaluation board is prepopulated and tested with a 12V, 73A hot-swap design, which is capable of working with a 3mF output capacitor.
