Overview

Actel’s Mixed Signal Power Manager (MPM) Daughter Card Kit enables system designers to

evaluate the functionality of Actel's power management solutions in hardware with a four-regulator

benchtop power management development system. The MPM Daughter Card includes four

regulators, four voltage bias potentiometers, and four fault introduction push-button switches,

implementing four fully independent power supplies that can be varied and interrupted to

demonstrate the management capabilities of Actel’s mixed signal power management solution,

MPM.

Connections, Jumper Switches, and Settings

Connect jumpers in the default settings to enable the MPM for SmartFusion design to function

correctly before powering up the boards.

• Jumpers from FB (feedback voltage) of each regulator for voltage trimming

– JP12, JP13, JP14, JP15 – Populated with jumper

• Jumpers for selection of PWM or SDD (see the MPM User’s Guide for details)

– JP17, JP18, JP19, JP20 – Connect pins 1-2

• Push-button switches to disable each regulator and simulate a power failure

– SW8, SW11, SW15, SW16

Push-button fault injection switches SW8, SW11, SW15, and SW16 ground the enable pin of the

corresponding regulator, thereby injecting failure in the power subsystem. However, this enable pin

is also connected to the pin on the SmartFusion FPGA (MPM_REG1_EN, MPM_REG2_EN,

MPM_REG3_EN, MPM_REG4_EN).The FPGA could be damaged if configured to drive High on

the enable line when the fault injection switch is pressed. To avoid this, Actel recommends that the

FPGA pin driving this enable should be driving Low or tristated.

MPM Demo Design Description

The MPM demonstration design takes advantage of the processing power and programmable

flexibility of the SmartFusion™ intelligent mixed signal FPGA on the SmartFusion Evaluation Kit

or Development Kit. Connect either kit to the daughter card and download the software as described

to run the demo.

The daughter card consists of four regulated power supplies running from a 9 V supply.

• National switching regulators for 1.5 V and 3.3 V

• Linear Technology and Artesyn DC-DC regulators for 5 V

Using the MPM design one can do the following:

• Monitor voltage for all rails

• Sequence different power rails for power-up and power-down

• Trim and margin a voltage rails in a closed loop

• Sweep the output voltage (POT circuit to change resistor on feedback voltage)

• Induce failures by disabling the enable input of regulator (push-button to GND enable)

Power sequencing is done by sequentially asserting or deasserting channel enable pins for power-up

and power-down, respectively, and monitoring the associated channel voltage. All enable pins to the

regulator are active high.

Software for MPM Demo Design

Download the MPM Executable which contains the demo design from the Actel website:

http://www.actel.com/products/hardware/devkits_boards/mpm_dc.aspx.

Run the demo design executable. This will install the MPM GUI. From the MPM GUI you can

program the demo design into the SmartFusion device and configure your power sequence or

trimming. You can update the sequence by uploading only the NVM register locations after the first

time you program the main design to the board.

Running the MPM Demo Design

With the SmartFusion Evaluation Kit – Connect the MPM daughter card to the A2F-EVAL-KIT

board. Connect both USB cables from your PC to the evaluation kit. One USB provides power and

UART connection; the other provides the programming connection. If you are using the daughter

card with the evaluation kit, you can remove the plastic legs and add the rubber feet supplied for this

purpose.

With the SmartFusion Development Kit – Connect the MPM daughter card to the A2F-DEV-KIT

board. Connect the 9 V power supply to the MPM Daughter Card and the 5 V power supply to the

development kit. It is a good idea to double check the voltages before connecting the supplies.

Connect the low-cost programming stick to the development kit and connect with a USB cable to the

PC for programming. Also connect the other USB cable to the USB connection on the board and to

your PC.

From the MPM GUI, select File > Write Device to load the MPM design to the device for the first

time. Use the switches on the evaluation or development kit to activate the power-up sequence. You

can then create interrupts and change POT settings to review the performance of the board. The

OLED shows the voltage of each of the first four power rails.

• SW1 initiates MPM power-up or power-down, depending on current state

• SW2 moves to the next OLED "screen" (e.g., next channel details)

To change the power sequence, use the GUI to change the settings and then do File > Write NVM to

update the register settings. It is not necessary to write the device again.

The demo design has many capabilities. To fully understand and use power management,

please refer to the documentation.
