  • TPS3110: Looking for a supervisor IC with a Watch Dog timer that has a time-out period of at least 2 seconds

    TI Thinks Resolved
    Part Number: TPS3110 Hello, In the TPS3110E15DBV, we noticed that the time out period is 1.1 seconds, do we have any alternatives that have a time out delay of 2 seconds?

  • what is the difference on the supply current vs supply voltage of the TPS3106 and TPS3110

    Other Parts Discussed in Thread: TPS3106 , TPS3110 Dear, i only read the tps3110 supply current vs supply voltage from the 7.8 Typical Characteristica of the datasheet. But i want to know the tps3106 supply current vs supply voltage. are they the same?or…

  • RE: TPS3110K33 WDI Input

    Resolved
    Hi Mitali, The TPS3110K33DBVR does not allow its watchdog to be disabled. If you do not need a watchdog timer, you could try the TPS3103 and TPS3106, both of which are from the same family as the TPS3110 and don’t have watchdog timers. Regards, …

  • RE: Regarding TPS3110K33DBVR supervisory watch dog input

    Resolved
    Hi Amit, The Watchdog timer is initiated when /RESET goes high. A transition on WDI must be generated during the timeout period (1.1s typically) after /RESET goes to the high logic level. If the DSP is taking more than the timeout period to boot and…

  • RE: Reset Watchdog

    Resolved
    Hi Christopher, TI has SVS products with a watchdog timer and monitors a 3.3V rail; however, there is not an SVS with a watchdog timer that has a VDD threshold voltage of 3.15V. Ususally, the thresholds are ~2.9-3.0V. However, a solution would be to use…

  • RE: LM3710/LM3711

    Resolved
    Hi Thibault, 1) I do not see a spec of the minimum pulse width you can pulse the WDI pin in the LM3710 datasheet. I recommend using the TPS3110 or TPS3823. This is speced as tw in the datasheet. 2) After the time-out period of the WDI signal, the RESET…

  • DM648 does not boot, nRESET at VCC

    Other Parts Discussed in Thread: TPS3110 Is a rising edge necessary for nRESET? Due to an error in the PCB the nRESET Pin is floating, to correct this without redesign it is now connected to 3,3V with a wire under the BGA. The nPOR Pin is connected to…
