Overview
The ICE Platform consists of daughter modules that are connected together through a common power
and communications bus. The daughter modules can be controlled by a master controller (ICE-MC1)
that performs power regulation, monitoring, and communications interfacing. All the circuit boards are
designed to the same template so that they can be stacked together to form a board-to-board bus
without the use of an additional backplane. An example of this stacking is shown below in
Fig. 1: ICE daughter modules stacked together.

  • Page 1 OEM Integration Guide Overview The ICE Platform consists of daughter modules that are connected together through a common power and communications bus. The daughter modules can be controlled by a master controller (ICE-MC1) that performs power regulation, monitoring, and communications interfacing. All the circuit boards are designed to the same template so that they can be stacked together to form a board-to-board bus without the use of an additional backplane.
  • Page 2: Power Requirements

    We invite you to join. Power Requirements Power Entry Power needs to be supplied to the power bus headers on all ICE circuit boards. These headers and respective supply voltages are shown in figure 3. The ICE master controller board (ICE-MC1) takes a single power entry point and distributes power to these headers.
  • Page 3 2019/05/01 00:16 3/17 OEM Integration Guide Fig. 3: ICE-MC1 Master and Control Board connector schematic (as viewed from component side). Power Entry Through ICE Master Controller Power is provided at J1 (Molex P/N: 0039303056). Pin definition shown in figure 3. The return current path for +5V_A is GND_A.
  • Page 4 Power Draw by Module The power supply capacity for the supply used to power the ICE stack must be sized appropriately to handle expected power draw for the modules selected. Current draw is listed in the specifications for each of the daughter modules.
  • Page 5: Power Sequencing

    ICE-MC1 master controller as it handles sequencing and startup commands automatically. The ICE power bus that distributes power to all daughter modules must have each voltage rail properly sequenced when turning power on and off. The ICE-MC1 master controller automatically takes care of this power sequencing to protect daughter modules.
  • Page 6: Power Button

    Power Button ICE-MC1 master controller is designed to allow a push switch to be wired up to turn on and shutdown the ICE stack. There is a 4-pin Molex connector (Molex PN: 22-05-3041) which allows for connection to a “OFF-Mom” style (normally off, momentary on) push switch and power for an LED to indicate power state.
  • Page 7 MOSFET controlled by another part of the OEM system. Mechanics Mounting The ICE stack needs to be mounted to a grounded chassis. Each ICE circuit board has mounting holes located in each corner for 4-40 thread standoffs. Please see the PCB Mechanical Specifications page for measurements and technical drawings.
  • Page 8: Thermal Management

    The Sil-Pad is shown in pink in figure 5 figure Further information on thermal management of the ICE boards, including CAD drawings of the heat sink clamp assembly, can be downloaded here.
  • Page 9: Board Connections

    Fig. 6: Detail of a clamping mechanism used to conduct heat with electrical isolation. Board Connections Each ICE daughter module exposes analog interfaces on the side opposite to the copper heatsink tabs. Each module's circuit board may use a mixture of the connectors described in this section. Each connector and an associated part number shown below such that the OEM integrator my chose a suitable mating connector for their system.
  • Page 10 OEM board for a diagram of the positioning of any connectors. For all ICE daughter modules, the circuit boards are designed such that all I/O connectors will be on a single side, and the copper heatsinking tabs will be on the opposite side. The master controller (ICE- MC1) also follows this convention, with the exception being the serial port flat flex connector.
  • Page 11 Standard 1.00 mm pitch FFC jumper cables can be used to connect to an FFC connector on the other end. The ICE system uses right angle, 1.00 mm pitch, bottom contact FFC connectors. Generally, the minimum bend radius for flat flex jumper cables is 2mm.

  • Page 16 The ID of this command is 7 and takes no arguments. To send the command, send an I C packet on one byte with the value of 0x07 to each ICE daughter module address (possible addresses are 0-7). In addition, the “Interlock” command should be sent to allow all modules that have a laser current controller to turn on.
