Configuring the UCD9081 through a method other than the GUI

Other Parts Discussed in Thread: UCD9081, TPS386000

Hi,

I am designing a system to sequence voltages to FPGAs in which I want to implement UCD9081 in the solution. However I cannot figure out a way to configure the chip without having to use the GUI and a USB to I2C interface. Is there any workaround to this solution, or is there any other sequencer from TI that is not programmable?

    We recommend using the GUI in order to generate your configuration of the device.  Once you have that configuration complete, you can use the GUI to generate a .hex file which can be programmed by your distributor, or using an I2C device programmer from a handful of programming equipment vendors.  You can also program the UCD9081 via I2C using a host CPU.  There is an app note on the UCD9081 product folder that outlines how to program the UCD9081 in this manner.

    One other option is to look at the TPS386000.  This device is a quad supply voltage supervisor that can be used as a 4 channel sequencer.  No programming required.  Just resistors and capacitors for adjusting your voltage thresholds and time delays. 

    I hope this helps.
