10. UG Power Supply Define DC/DC Voltages Power On Control for 12/29V Isolate Subsystems Latch-Up Protection Monitor Operation m.d.i. 6031-S28 29.0V ordered m.d.i. 6031-S12 12.5V ordered Controller for m.d.i. DC/DC major effort Would not protect individual UG-boards

11. UG-Electronics Latch-Up Protection for UG-Board Components: - 54SX 208/32A FPGA - LM2941S 12V-> 10V LinReg - TPS7350 5V-> 5V LinReg - TPS7333 3.3V->3.3V LinReg - TPS7325 2.5V->2.5V LinReg - SN65LVDS390 LVDS-Driver - AD7476 ADC for P-Sensors - Si4840DY MOSFET Heater/MV Control - SUB65P06-20 MOSFET Heater/MV Enable - SUB85N10-10 MOSFET Heater/MV switch - LM239A Comparator MV Sense - Si4544DY MOSFET FV - Si4966DY MOSFET FV - MAX225EWI RS232 Driver - HI-508 Analog MUX - AD620BR UGPS Diff.Amplifier + TRD-GAS P-Sens., TubeAmp, MCA, Spirometer Open Item List Safe 29V for Kulite Sensors Separate 5V for TubeAmp Separate 12V for FV/UGPS - EM System working at RWTH - QM System at Rome with new prototype backplane Schedule: - QM backplane prod. in Feb. - QM SQ in Mar/Apr. at SERMS

12. Problem 1 Kulite Sensor Supply Current Design: 29V supply directly from backplane 29V-A and -B connected at sensor Loss of redundancy Risk of losing Marotta Valve actuation power Proposal: Diodes and 1k  Resistor at sensor in Box-S Decision needed for FM Box-S wiring at MIT Also twisted pairs needed to reduce noise

13. Problem 2 TubeAmp Supply 5V shared with RS232 and ADCs Risk losing only abs.press.sens. in TRG Gas volume Proposals a)Supply from UGBC-A only b)Add separate 5V LinReg c)OVC protect. On TubeAmp

14. Problem 3 UGPS Supply 12V shared with Flipper Valves Risk losing FV actuation power Proposal: Add separate 12V LinReg

15. Simple UGPD Control Without OVC / latch-up protection Keep UG boards and backplane Passive control of 12V and 29V m.d.i. converters Simple board in UGPD – No Controller Delayed power on after 5V on Switched off when 5V off

16. UG Power Control Board Replace UHVG in UG-Crate Gasgain monitor HV from U-Crate + Provide individual board SSF for 3.3/5V and Control of 12/29V + No modifications of UG-Boards + No Controller in UGPD – Redesign UG backplane discussed with Capell & Lebedev, W.Karpinski may design, 20k€ required
