  • TPS386000: WDO output issue on TPS3800

    TI Thinks Resolved
    Part Number: TPS386000 Hi , We are using TPS386000 part. As per datasheet Watchdog timer (WDT) trigger input. Inputting either a positive or negative logic edge every 610 ms (typical) prevents WDT time out at the WDO or WDO pin.we are giving 5hz signal…

  • TPS386000: Maximal current via output RESET pin

    TI Thinks Resolved
    Part Number: TPS386000 Dear TI, according to datasheet of TPS386000, the maximal current via output RESET pin is 5 mA. Except of pull-up resistor at RESET line, I have a small capacitor (several nF) connected between RESET and ground. From measurement…

  • TPS386000: Strange component marking and the label of the Reel

    TI Thinks Resolved
    Part Number: TPS386000 The component from the picture under was contained in the Reel with the label from the picture under. Q1: Is the Reel relabeled? Q2: Is this component marking valid? Is the quality of the component marking according to TI norms…

  • RE: TPS386000: change TPS386040

    Hi Balaji, Having the RST outputs of the 6040 OR'd will not cause issues. Jesse

  • TPS386000: Schematics Review

    TI Thinks Resolved
    Part Number: TPS386000 Hi Team, I am using TPS386000RGPR in my design. I would like to get the circuit design get reviewed by experts. TPS386000.pdf I would also like to get a cofirmation regarding the unused pin status of WDO#, WDI and VREF. Whether these…

  • TPS386000: CTn Voltage Delayed on Single Channel

    TI Thinks Resolved
    Part Number: TPS386000 Our design has 5 voltage rails that are connected to the SENSEx inputs on two TPS38600 devices - V1 (SENSE1-1), V2 (SENSE1-2), V3 (SENSE1-3) and V4 (SENSE1-4) on device 1 and V5 (SENSE2-1) on device 2. Note that VDD of both devices…

  • RE: TPS386000: Desgin Analysis

    Hi Shifali, The WDIn and WDO pins can be left floating. In that case, WDOn will assert low (due to no logic transitions from WDI) but the RESETxn pins will not. WDOn is connected to SVS-1 in the sense that a reset of RESET1n needs to be reasserted in…

  • TPS386000: How should we overcome watchdog timer at startup

    TI Thinks Resolved
    Part Number: TPS386000 Other Parts Discussed in Thread: OMAPL138 We are having an issue overcoming the watchdog timer of the power supervisor during powering on our system. Are there any recommended ways of doing this correctly? We have an OMAPL138 as…

  • TPS386000: Country of Origin and REV question

    Resolved
    Part Number: TPS386000 Dear TI, I would like to ask what is the difference between REV A and B of TPS386000RGPR. I found on TI website this part has multiple assembly site. Is that possible if the chip country (CCO) is Japan, then the parts are ROHS…

  • TPS386000: Reset Delay Time Error

    TI Thinks Resolved
    Part Number: TPS386000 We're using a TPS38600 which monitors 4 different rails, each using a 22 nF capacitor on the Cct pin. Per the equation pulled from the datasheet, Cct(nF) = [Tdelay(ms) - 0.5(ms)] X 0.242, we would expect a delay time of around…
