  • UCD90160: introduction of UCD90160

    TI Thinks Resolved
    Part Number: UCD90160 Other Parts Discussed in Thread: UCD9090 Hi team, Our customer uses UCD90160. Can we give a basic introduction of UCD90160? They don't know how to use it. By the way, what's the difference between 90160 and 9090? Thanks for…

  • UCD90160: floating GPIO pins behavior

    TI Thinks Resolved
    Part Number: UCD90160 I have floating GPIOs pins on a UCD90160 design. If I do not set these IO in the pin assignments - what does the IC do with that pin? Is there a weak pullup/down internally that gets set? Or should I set them in the GUI to something…

  • UCD90160: what is the maximum value for MON pin voltage sense?

    TI Thinks Resolved
    Part Number: UCD90160 Hello expert, My customer would like to decrease current consumption so they want to know the maximum voltage divider for 3.3V and 3V. Right now they put voltage divider R1/R2 = 4.02kohm/4.02kohm and they think current consumption…

  • RE: UCD90160: an NACK issue with a combined command

    Hi Yihe, What waveform do you need? Previously, a customer shared the waveform of getting NACK and ACK after writing the 0X80 command. Getting NACK Hailiang Zhang said: I see your reply is about the waveform of i2cget -y -f 8 0x34 0x80. Yes, it has the stop…

  • UCD90160: configure time of fault response setting

    Resolved
    Part Number: UCD90160 Hi team, I use GPI to configure the fault response. Use low GPI input to ignore the fault. If GPI and monitored power are pull low together, will UCD90160 have a fault response? After I GPI reach low threshold, what's the time…

  • RE: UCD90160: [Consultation] UCD90160RGCR FW programming function check (errata/sighting) and IC stepping difference (UCD90160 vs UCD90160A)

    Resolved
    Hi Yihe, I think UCD90160 A or non-A have supported background mode programming into memory and would take effect after reset. I'll select UCD90160A which has more feature to design in my system for power management. Thanks. Best Regards, Paul Le…

  • RE: UCD90160: Migrating the design from UCD90160 to UCD90160A.

    Hi Yihe, Thanks for the information. yihe said: Are you sure 3V3 is connected to the UCD? Yes, surely it was connected to UCD. There are other devices on the same rail like MSP430 which were all coming up when powered from other power source. -- Regards…
