Hi,
We are designing in a LM01502 device but I see no mention of the SPI electrical parameters on the LM10502 datasheet outside of SPI max frequency of 10MHz. We are running a SPI interface of only 38KHz and the device is not responding to SPI commands on Buck1 or Buck2. Is there a minimum frequency or minimum slew rate for the digital interface? We have a logic analyzer hooked up to a test board and the SPI commands and addresses are valid per the logic analyzer. We have probed the data all the way to the signal input of the mounted LM10502 device to confirm that the data stream is getting through the test board. Is there a undocumented startup procedure via SPI that is not mentioned in the datasheet?
