The board is designed to power up with a 9 V input supply that can be turned on and off using a dedicated switch (Switch S1, ON/OFF). The two ADM1087 devices on the board can be enabled and disabled using another switch (Switch S2, ENABLE/DISABLE). When enabled, the ADM1087 devices on the board monitor a voltage rail and turn on the corresponding three ADP3334 LDO devices in a sequence. LEDs on the board provide a direct visual indication of the sequencing of three different voltages: 3.3 V, 2.5 V, and 1.8 V. EVALUATION KIT CONTENTS ADM1087 evaluation board Complete specifications for the ADM1087 can be found in the ADM1087 data sheet, available at www.analog.com, and should be consulted in conjunction with this user guide when using the evaluation board. 11837-001 PHOTOGRAPH OF THE EVALUATION BOARD Figure 1.

The board functions as follows: The EVAL-ADM1087EBZ is designed to demonstrate the features of the ADM1087 sequencer. A simplified block diagram of the evaluation board is shown in Figure 2. 1. Two ADM1087 devices are used to sequence the outputs of three ADP3334 LDO regulators. Separate capacitors on the CEXT pin of each ADM1087 device determine the time delays between enabling the 3.3 V, 2.5 V, and 1.8 V supplies. The LDO regulators and ADM1087 devices are connected in a cascade; therefore, the output of each regulator is dependent on the output of the previous device. 2. 3. 4. There are two switches included on the board: • The S1 switch (ON/OFF) is used to power up or power down the board. The S2 switch (ENABLE/DISABLE) is used to enable or disable the ADM1087 devices. S1 SD IN ADP3334 D1 OUT 3.3V SD Q1 IN ADP3334 D2 OUT 2.5V 3.3V D3 OUT 1.8V Q3 VCC VIN ENOUT ADM1087 ENIN IN ADP3334 3.3V VCC VIN SD Q2 ENOUT ADM1087 CEXT ENIN CEXT 9V S2 11837-002 • Place the S1 switch into the ON position to turn on the first ADP3334 LDO regulator. The ADM1087 devices monitor the output of this regulator. When the output reaches 3.3 V, the red LED (D1) illuminates and the second ADP3334 LDO regulator turns on. The ADM1087 devices monitor the output of this regulator. When the output reaches 2.5 V, the yellow LED (D2) illuminates and the third ADP3334 LDO regulator turns on. The ADM1087 devices monitor the output of this regulator. When the output reaches 1.8 V, the green LED (D3) illuminates. Figure 2.
