Abstract:
A power detection circuit includes a sense element to convey current from a source to a load, a compensating reference element located proximate to the sense element, a comparator, and a precision current sink. The comparator includes a first input coupled to the sense element, a second input coupled to the compensating reference element, and an output. The comparator is configured to assert a signal on the output in response detecting that a first voltage on the first input equals a second voltage on the second input. The precision current sink is coupled to the second input of the comparator and is configured to pull constant current through the compensating reference element based on a predetermined power threshold.
Abstract:
A power supply system includes at least a first power supply module and at least one redundant power supply module. The at least one power supply module supplies power to an output terminal. The at least one redundant power supply module operates in a first state and in a second state. In the first state the second power supply module supplies power to the output terminal. In the second state the second power supply module provides standby power and operates in a burst mode (for example, such as a discontinuous conduction mode).
Abstract:
A power supply system includes at least one power supply module and at least one redundant power supply module. A power supply module may include a charging resistor in parallel with an OR-ing device to keep all filter capacitors charged as long as at least one power supply module remains operational. This may avoid current spikes at turn on and may enable the redundant module to turn on without using soft start.
Abstract:
Disclosed herein are integrated circuit (IC) package support structures, and related systems, devices, and methods. In some embodiments, an IC package support structure may include a first heater trace, and a second heater trace, wherein the second heater trace is not conductively coupled to the first heater trace in the IC package support structure.

Abstract:
Integrated circuit chip attachment is described using a local heat source. In one example an interposer has a top side to connect to a silicon component and a bottom side to connect to a circuit board, the top side having a plurality of contact pads to electrically connect to the silicon component using solder. The interposer a plurality of heater traces having connection terminals. A removable control module attaches over the interposer and silicon component to conduct a current to the heater connection terminals to heat the heater traces, to melt a solder on the contact pads of the interposer and to form a solder joint between the component and the interposer.
