Most companies see only the manufacturing costs, but the en- gineering-resource allocation is what keeps most projects from completing on Dallas MAX9726. EDN Contact me at pallahc siliconmap.

Trademarks are the property of their respective owners. I designed an 'processor-based USB periph- eral with external memory. The power supply was more complicated than usual due to the requirements Dallas MAX9726 this device: It needed USB power regulated to 33V dc, boosted up to 6V dc, and then regulated back down to create a 5V- dc reference.
Dallas MAX9726 Some units were slow to start up, and some would not start at all. We cycled power off and then back on, and they would all then work.

Initially, I couldn't reproduce the problem in the lab. All of the power-supply compo- nents were operating well Dallas MAX9726 their rated capacity, and the reset circuitry was triggering at the correct voltage level.

I added an external reset switch to the board to let me better examine the reset process and discovered that, when I held the processor in reset, the 5 V-dc supply voltage dropped below the reset chip's threshold voltage, which was the Dallas MAX9726 cause of the boot-up failure. Further investigation showed that the USB-supply current increased to al- Dallas MAX9726 double its normal value while the processor was in reset.

This doubling of supply current exceeded the current rating of the 3. This drop, which greatly increased current draw while the processor was in reset, was definitely not something I had expected to see. I started debugging the problem by measuring the current draw of each chip on the PCB Dallas MAX9726 board. Ev- erything was nominal until I got to the latches.

Instead of the microamp cur- rent draw Dallas MAX9726 was expecting to measure, Dallas MAX9726 one was drawing 20 mA. After the processor came out of reset, the extra current draw stopped, and everything began operating normally. We were us- ing the latches correctly according to their data sheet, and the system func- tioned properly after reset.
Disconnect- ing the external memory didn't change Dallas MAX9726 reset current draw into the latches. After some fruitless investigations of the latches and external circuitry, I turned my attention to the processor. Port of the processor is unique in that it has no internal pullup resistors like the other ports on the processor. This fact gave me an inkling of what might be the root cause of the problem. The data sheet defines the port pin's state on exiting reset but doesn't define the state while the processor is in reset. It turns out that Port goes into high- im- pedance open-collector mode when the processor is in reset.
This scenario leaves the inputs to the latches floating, which is undesirable. I added external pullup resistors to the Port processor pins, eliminating the problem.
We had taken this memory- expan- sion design directly from the Intel data book, and we have used Dallas MAX9726 in many designs over the past 25 years without ever seeing a problem. In retrospect, I realized that all of these designs must also draw additional current while in reset, but no one had noticed this re- quirement before because none of Dallas MAX9726 designs have power supplies with such strict current limitations. Designers would have attributed any current spike at start-up to inrush current and would have ignored these spikes.
