Quad Voltage Monitor and Sequencer GENERAL DESCRIPTION The EVAL-ADM1185EBZ evaluation kit demonstrates how the ADM1185 can provide quad voltage monitoring and sequencing in multiple supply systems. The ADM1185 monitors four separate voltage rails, turns on three regulators in a predefined sequence, and generates a power-good signal when all supplies are operating and stable ...

... Place a single sample in the socket before powering on the evaluation board. POWERING THE EVALUATION BOARD There are two methods of powering the EVAL-ADM1185EBZ, by either connecting power supply through connecting a bench supply through J1 (the 9 V and ground leads must be connected separately). When using power supply, ensure to switch S2 to the 9 V position ...

... EVAL-ADM1185EBZ OBSERVING FAULT CONDITIONS FOLLOWING POWER ON If all four supply voltages are above their associated threshold, PWRGD asserts and the logical core latches into a different mode of operation. If the 3.3 V supply monitored by VIN1 faults while the device is in the power-good state, the PWRDG output is deasserted and all of the outputs are immediately turned off ...
