| "queryText" : "Part Number: PTD08D210W Hi, I found that PTD08D210 is generating a voltage of 5.9V even when the UCD9248 is not configured. PTD08D210 has two power output and this problem is seen only in one channel, I even erased the UCD Flasmemory and confirmed that no PWM is going to PTD08D210 but still i see 5.9V in one of the channel. Note: My evel board has 4 PTD08D210 which means 8 o/p voltage channels and 2 UCD9248 to control it , out of which in only one channel i have this problem. Is it the problem with the PTD08D210 , it was working fine only suddenly in one day this problem happened.", | |

| "content" : "Hi, Alejandro One sudden day we noticed our DDR Not working, then when we checked the voltage going to DDR section from PTD it was 2.5 V instead of 1.5 V, then when we isolated the DDR , WE found that the voltage from PTD IS 5.6 V half of the input voltage to PTD AND UCD., We earsed the UCD Flash memory to and even when no PWM IS going to PTD it generates 5.9 V. I just thinking to change the PTD and see." | |

I will let yu know once we receive and test it. Thanks!" | |
