Part Number: UCD9090A Tool/software: hi guys,
i have few UCD9090A device with different address, one of it we accidentally program with -pflash command. and causing the device go into ROM mode.
everytime we cycle the power, the device fail to output…
Part Number: UCD9090A Tool/software: Hello,
In our board, we have two UCD9090A devices for monitoring the voltage rails. We have connected both the devices to our Intel processor via I2C bus. Our application requires us to store the Power supervisor…
Hi,
Since there are no issues when using the TI USB adapter, there does not appear to be any issue with the UCD9090A device itself, only with communication with between it and this specific master device.
I suggest comparing the SCL and SDA waveforms…
Hi Yihe,
Based on Nelson's waveform. Alert pulls down and the rails that is monitored are still in low level.
Nelson Chang said: capture during the power up.
Is it a correct behavior?
Is UCD9090A detected the rail too early?

Part Number: UCD9090A Tool/software: i have two mon pins Governing rails of the same sequence order,since its the end should i leave the mon pins to just monitor or should i add reset signal assigned right after to it?that to for both mon pins?
Part Number: UCD9090A Tool/software: I can see the mon pins of UDC9090A and i have assigned rails to monitor it,and now my doubt is if the fault occurs how the monitoring functions actually works?i read PMBUS ALERT pin plays a major role in monitoring…
Part Number: UCD9090A Tool/software: Hi Expert，
The customer uses the black box function of UCD9090A to record fault information. If rail A or rail B fails, the system will be powered off. Since the timestamp of the fault is at the second level, multiple…
