EVAL-ADM1186-1EBZ

Evaluation Kits for ADM1186 Quad Sequencer and Monitor EVAL-ADM1186 FEATURES 4 on-board variables supplies with LEDs to show status LEDs to show power good, fault, and sequence done (main evaluation kits only) Switchable capacitors to set time delays (main evaluation kits only) Manual fault push switch Single step mode Multiple boards can be cascaded for more than four supplies (EVAL-ADM1186-1EBZ only) PRODUCT DESCRIPTION The ADM1186-1 and ADM1186-2 can be used to turn on and off four supplies in sequence under the control of a state machine, and can monitor the supplies to ensure that they are above a user defined undervoltage (UV) threshold. If any supply drops below the UV threshold, a fault occurs and the state machine turns all the supplies off. GENERAL DESCRIPTION There are two types of evaluation kits for the ADM1186-1 and ADM1186-2. The main evaluation boards are intended for standalone operation of the devices with just an external mains power supply. They provide all the on-board supplies, controls, and status indicators necessary to operate the device. The micro-evaluation boards are intended to allow the ADM118-1 or ADM1186-2 to be easily used as part of a bench prototype, and include the minimal set of components. The evaluation kits for each device allow a user to perform controlled up and down sequences of four supplies. The main evaluation kits allow simulated fault conditions on each on-board supply or on a control signal. All kits provide the ability to single-step and observe the behavior of the state machine during the power-up and power-down sequence. A single ADM1186-1 can control four supplies, but it is possible to join multiple devices and boards together to support cascaded up and down sequences of eight, 12, or more supplies. The main ADM1186-1 evaluation board supports a daisy-chain connection to demonstrate this feature. EVALUATION KIT CONTENTS The EVAL-ADM1186-1EBZ and EVAL-ADM1186-2EBZ evaluation kits contain an evaluation board, along with some samples of the ADM1186-1 or the ADM1186-2 parts. The EVAL-ADM1186-1MBZ and EVAL-ADM1186-2MBZ micro-evaluation kits contain only an evaluation board. For all types of evaluation kit, an ADM1186-1 or ADM1186-2 device is present and soldered to the board.

The center of the barrel jack connector is ground. The input pins, VIN1 to VIN4, monitor one of four supply voltages. The VIN1 pin monitors the 3.3 V rail. An external resistor divider scales this voltage down for monitoring at the VIN1 pin. The resistor ratio has been chosen so that the VIN1 voltage is 0.6 V when the 3.3 V rail is 5% below its nominal value. For example, if R1 is 100 kΩ and R2 is 23.7 kΩ, a voltage level of 3.13 V corresponds to 0.6 V at the VIN1 pin, as shown in Figure 3. A switch, S1, selects which of the two supply options (jack or term) is used by the board. At no time should a supply connection be made to both J1 and J3. V 3.3V 3.13V 0V 100kΩ 3.13V SUPPLY GIVES 0.6V AT VIN1 PIN GETTING STARTED This section demonstrates the basic operation of a main evaluation board, performing a simple up and down sequence. The detailed operation and configuration of the board is covered in the following sections. To configure a single board to perform an up and down sequence, use the following steps: 1. 2. 3. 4. 5. Set S2 to the down position. Set the S3 to S7 switches to the Seq position. S3 is present only on EVAL-ADM1186-1EBZ. Set switch banks S8 to S12 such that only Switch Position 2 on each bank of switches is on. S8 is present only on EVALADM1186-1EBZ. On EVAL-ADM1186-1EBZ, ensure that jumpers are fitted on J8 to J10. Ensure that jumpers are fitted in positions J4-A, J5-B, and J6-B. Only J4 is present on EVAL-ADM1186-2EBZ. Turn VR1 to VR4 so that they are fully clockwise. Connect an appropriate supply to either J1 or J3 and set Switch S1 accordingly. The D1 and D2 LEDs should be on. Change Switch S2 to the up position to start an up sequence. The four supplies turn on, shown by LEDs D3 to D6. The PWRGD (power good) and SEQ_DONE (sequence done) LEDs, D7 and D8, are also turned on at the end of the up sequence. Setting S2 to down reverses the sequence, turning off the LEDs. t ADM1186 VIN1 27.2kΩ 0.6V TO LOGIC CORE 07620-003 When multiple EVAL-ADM1186-1EBZ boards are cascaded together, power needs to be applied to a single board. Switch S1 must be set to the same position on all boards, depending on whether the terminal block or barrel jack is in use. This should be done before power is connected. Figure 3. Setting the Undervoltage Threshold with an External Resistor Divider Board Supplies The board supply of 5 V is used to generate the four rails monitored by VIN1 to VIN2. The four other rails are nominally 3.3 V, 2.5 V, 1.8 V, and 1.5 V, but can be varied by about ±10% using the variable resistors VR1 to VR4, respectively. This range is sufficient to allow the user to set a supply above or below the UV level to simulate undervoltage faults during a sequence or once powered on. Capacitor Timing and Single Stepping The ADM1186-1 provides five timing pins, four used for sequence delays and one for a blanking time. The ADM1186-2 provides four timing pins, three used for sequence delays and one for a blanking time. A capacitor on each pin sets the time delay for a given state during an up or a down sequence. The evaluation boards provide three fixed value capacitors for each sequence delay that can be individually switched in or out, as required, using S8 to S11 (S8 is found only on EVAL-ADM11861EBZ). The capacitor values fitted are 10 nF, 100 nF, and 1 μF, giving approximate delay times of 1 ms, 10 ms, and 100 ms. The evaluation boards provide three fixed value capacitors for the blanking delay that can be individually switched in or out, as required, using S12. The capacitor values fitted are 10 nF, 47 nF, and 100 nF, giving approximate delay times of 1 ms, 5 ms, and 10 ms. Rev. 0 | Page 9 of 24 EVAL-ADM1186 PIN 1 There is also provision for user capacitors to be fitted to the board that may be switched in for additional sequence or blanking delay time options. For all capacitors, the duration of the time delay is defined by the following formula: Refer to the relevant state machine diagram in the ADM1186 data sheet for the details of when the capacitors are used during the power-up and power-down sequences. Manual Fault Generation The EVAL-ADM1186-1EBZ provides a push switch, S13, that can be used to generate a fault condition by bringing the FAULT line low for as long as the switch is pressed. While S13 is pressed, the D9 LED is lit to indicate a fault condition. The delay control switches can be used to pause the state machine and examine its behavior under various fault conditions. For example, setting the Delay 2 control switch to hold prevents the state machine from advancing to the ENABLE OUT2 state. This allows a user to simulate a UV condition on the 3.3 V supply in the Delay 2 state that is otherwise difficult to achieve. SEQ_CNTRL SEQ_CNTRL SEQ_DONE_N SEQ_DONE_N + 1 07620-004 The S3 to S7 switches are set to the sequence position for normal operation (S3 is found only on the EVAL-ADM1186-1EBZ). Setting a switch to the hold position grounds the timing pin, preventing the capacitor from charging and effectively pausing the state machine. SEQ_DONE_N Associated with each group of capacitors on a timing pin is a switch that can be used to hold the state machine in a specific state. This function allows the user to single-step through an up or down sequence, and manually control when the next state change occurs. PWRGD BUS 5V where: tDELAY is the time delay in seconds. CDELAY is the capacitor value in microfarads. FAULT BUS tDELAY = CDELAY × 0.1 SEQ_DONE_N – 1 J2 J11 PIN 1 Figure 4. Pin Connections for the Cascade Connectors on Board N Figure 5 shows how boards should be connected in cascade and the order in which the twelve supplies are turned on, from 1 to 12. In the power down sequence, the order is reversed so Supply 12 is turned off first and Supply 1 is turned off last. There is a pair of jumpers on EVAL-ADM1186-1EBZ that needs to be set to connect the sequence up and down control signals. Jumper J5 and Jumper J6 should be set according to Table 3. For example, Board A would have J5 in Position B and J6 in Position A. When all boards are configured, Switch S2 on Board A is able to control the up and down sequence for all cascaded boards. ADDITIONAL BOARDS IN CASCADE J11 BOARD C SUPPLIES 9 TO 12 CASCADING MULTIPLE BOARDS J2 The ADM1186-1 provides additional pins and functionality that enable multiple devices to be cascaded, while still maintaining a controlled power-up and power-down sequence. J11 The J2 and J11 connectors are used to daisy-chain the EVALADM1186-1EBZ boards to cascade multiple devices. When connecting the boards together the order is important as this sets the place in the power-up/power-down sequence. The pinouts for the two connectors used for cascading boards are shown in Figure 4. BOARD B SUPPLIES 5 TO 8 J2 J11 BOARD A SUPPLIES 1 TO 4 J2 NO CONNECTION 07620-005 The EVAL-ADM1186-1EBZ supports the cascading of multiple boards so that the behavior of multiple ADM1186-1 parts controlling eight, 12, 16, or more supplies can be demonstrated. Figure 5. Connecting Multiple EVAL-ADM1186-1EBZs in Cascade Rev. 0 | Page 10 of 24 EVAL-ADM1186 Jumper J8 and Jumper J10 allow the isolation of the PWRGD and FAULT signals to individual boards. When the jumpers are fitted, the PWRGD or FAULT signals of each board are connected to the PWRGD or FAULT bus. If the PWRGD signals from all the boards are joined to the PWRGD bus, then the PWRGD signal is active only if all supplies are above their UV threshold levels. If the FAULT signals are all joined to the FAULT bus, a fault on any one board causes all other devices to enter their fault handler states as well. When multiple ADM1186-1 parts are used in cascade, their FAULT pins are typically connected together to ensure that the power-up and power-down sequence works correctly. Finally, Jumper J7 and Jumper J9 are used to connect pull-up resistors to the PWRGD and FAULT pins on each board. The pull-up resistors are connected to the VCC supply rail, selected by J4, for a given ADM1186-1. If multiple PWRGD or FAULT pins are connected together, particularly if the ADM1186-1 devices are being powered from different supply voltages, then only one J7 or J9 jumper should be fitted on all the boards in cascade. MICRO-EVALUATION BOARD The micro-evaluation boards can be used to easily create bench prototypes of a power system. The ADM1186 micro-evaluation boards provide all the minimum components necessary to sequence and monitor four external dc-to-dc power modules or LDOs. Each micro-evaluation board provides precision resistors for scaling to monitor 3.3 V, 2.5 V, 1.8 V, and 1.5 V rails, and capacitors to set the sequencing and blanking delays. A pull-up resistor is also provided on each open-drain output to ensure correct operation. A bank of switches is provided to enable the single-step operation of the state machine. These switches operate in the same ways as the Delay x control switches on the main evaluation boards. Turning on a switch grounds a time capacitor and holds the state machine in the given state if that capacitor is being used to control a time delay. One of the switches on the EVAL-ADM1186-1MBZ is connected to the FAULT line and can be used to generate a fault condition, if required.
