Refer to the timing diagram in Figure 1. Whenever SS is above 2.2V and the EXTVCC LDO is not switched over (the EXTVCC pin is below the switchover threshold), the internal 10μA pull-up current on SS turns off and a 5μA pull-down cur- rent turns on, discharging SS. Once SS ...
1kHz is a good starting point to optimize peak measurements, but some fine tuning of this selection may be necessary to get the best overall EMI results in a particular system. Consult factory application for more detailed information about EMI reduction. 50 40 30 SPREAD SPECTRUM DISABLED 20 10...
Product Enquiry: “ABC Lane for automated Border Control” My company is currently working on a high level cost plan for an airport and I was wondering if it would be possible to be provided with a budget quote for your ABC Lane/ e-gating system. Sent to Airport Suppliers Company Butiks...
The room studied in this related experiment had seating for six around a central table, a chilled beam conditioning system, a larger double-glazed window, and exhaust through the doorway. Both the conference room [54] and classroom studies were modeled in Ansys Fluent with similar boundary ...
System Power-Up Timing (All Waveforms Are Referenced to VEE) At time point 8, the load current falls and the SENSE voltage drops below VACL(t). The analog current limit loop shuts off and the GATE pin ramps further. At time point 9, the SENSE voltage drops below VCB, the fault TIMER...
Making PCB Connections to the Sense Resistor TIMING WAVEFORMS System Power-Up Figure 7 details the timing waveforms for a typical power-up sequence in the case where a board is already installed in the backplane and system power is applied abruptly. At time point 1, the supply ramps up, ...
As with traditional voltage regulators, when VFB rises near or above the reference voltage of EA (1.2V typical, see Block Diagram), the ITH voltage is reduced to command the amount of current that keeps VOUT regulated to the desired voltage. Constant-Current Regulation (IAVGSNSP and IAVGSN...
Refer to the timing diagram in Figure 1. Whenever SS is above 2.2V and the EXTVCC LDO is not switched over (the EXTVCC pin is below the switchover threshold), the internal 10μA pull-up current on SS turns off and a 5μA pull-down current turns on, discharging SS. Once SS ...
When the system wakes, one might send an external clock to PLLIN/SPREAD, or tie MODE to INTVCC to switch to low noise forced continuous mode. Such on-the-fly mode changes can allow an individual application to benefit from the advantages of each light- In general, the requirements of ...
A 4.5V to 38V input supply range encompasses a wide range of system architectures and battery chemistries. When biased from the output of the boost converter or another auxiliary supply, the LTC3787 can operate from an input supply as low as 2.5V after start-up. The operat- ing frequency ...
