Power management standardisation across PCBs
The new Power604 from Lattice Semiconductor offers a versatile, value-for-money approach to power sequencing.
"We were able to resolve our power supply sequencing and supervisory problems quickly by using the Lattice ispPAC Power Manager devices", said Lionel Defrance, Digital Hardware Engineer, and Vincent Vieu, Manager of the Digital Hardware Department of Thales Airborne Systems.
"Not only was the board design greatly simplified by the flexibility and superior performance of the ispPAC-POWR1208 devices, but, as a single-chip solution, the Power Manager also provided a 30% savings in the circuit board area".
"We are now standardising on ispPAC Power Manager-based solution across multiple boards in our signal and image processing system".

Thales also used the device in a high-voltage environment and found no performance degradation.
Thales concluded that the Lattice ispPAC Power Manager devices will not only simplify analogue design, but will increase the efficiency of the entire system design process as well.
The ispPAC-POWR1208 devices integrate Lattice's industry-leading ispMach CPLD with ispPAC programmable analogue technologies to create a single chip that provides a versatile, cost effective and convenient response to Thales' system design challenges.
The ispPAC-POWR1208 performs multiple functions in the Thales system.
For example, an embedded ispMach CPLD, designed to operate under noisy power supply conditions, is used for sequencing, monitoring and supervisory signal generation; the device provides precision programmable threshold comparators to monitor up to 12 power supply voltages; programmable delay timers plus an internal oscillator are used for flexible timing control; and programmable high voltage MOSFET driver outputs control supply ramp rate.
"Customers such as Thales implementing complex analogue designs can take advantage of Power Manager features that include integrated resistors, capacitors, sense amps, FET drivers and control logic, all provided in a single, low-cost, programmable power management chip", said Steve Stark, Director of Product Marketing for Lattice.
Lattice's Power Manager devices provide a standard, off-the-shelf programmable mixed-signal solution for power management that enhances reliability and speeds time-to-market.
Analogue features such as input comparator thresholds and digital functions such as supply control sequences are programmed into nonvolatile E2CMOS elements on the devices using an IEEE1149.1 boundary scan protocol.
Applications for Power Manager devices include a broad variety of electronic equipment, including telecom and networking systems, storage systems, servers, test equipment and automotive electronics.
Their programmable features make them ideal for controlling multiple power supplies in conjunction with a wide range of regulator and switching technologies.
