Hi
I am looking for source of ESD Diodes at SIM area.
I only know Murata, Semtech and On semi...
Do you have any other brand suggest with part number?
Thank you.
Hi All,
Currently I am designing a power management system for GPRS modem.
The input power is 10V/100mA. The VBATT programmed from DC-DC Buck Regulator (LM3845) is set to 4V. DC-DC Buck Regulator has current limit protection function. So i programmed it to 100mA also.
Pout = Pin x...
USB port will hang if USB hub is used.
The USB hub is used for multiple products flashing. ( 8 in 1 Flashing)
Any one here know about the reason?
Need to do any clear Port using Regedit?
How to clear?
Thank you
I have a question.
There is always RMA from the customer side. We, as designer house, will only can send the failed IC to the supplier for failure analysis.
From the IC failure analysis, they will always blame ESD or EOS as the cause of the failure. However, they never specify what thing will...
THIS IS THE REPLY FROM MAXIM TECHINCAL SUPPORT TEAM:
Mail 1:
I wanted to make sure my research was relatively thorough before

Ya, In RS232 protocol both party are allow to initiate communication. But if the situation is like this:
UART ----(a)------> UART to SPI converter (Slave) --(b)---> Microcontroller's SPI master
(a) "communication OK" (b) "I doubt the communication here!"
Hope you...
Sorry for making you confusing. Let me explain again: I have a micro controller which only has one UART port. But I need to have 2 UART for a certain project. Therefore, i need to create a UART port from the micro controller's SPI port.
We need a SPI to UART converter (such as MAXIM3100 or NXP...
spi to uart converter
A micro controller only has one UART port. Therefore, we decide to use microcontroller SPI port as another UART2.
We need a SPI to UART converter (such as MAXIM3100 or NXP - 161S752), however, this IC only supports SPI slave mode only. When we use it with this...
