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.

EVAL-ADM1186 EVALUATION BOARD OPERATION POWER REQUIREMENT Setting Voltage-Detection Levels The evaluation board requires a supply rail of 5 V, which can be provided in one of two ways: either a dc supply of 5 V can be directly connected to the terminal block, J1 with polarity as marked on the PCB, or a 9 V dc supply can be connected to the J3 barrel jack connector, which is then regulated down. The center of the barrel jack connector is ground.
PAGE 10
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.
PAGE 11
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.
