Part Number: TPS3610 Hi.
When the WDI pin of the TPS3610 was left open, I observed a pulse with a period of about 700ms. Is this the signal the TPS3610 outputs itself to reset the internal watchdog timer?
CH4 is the WDI pin waveform.
When I…
Part Number: TPS3610 Hi team,
Could you give me comment on following customer questions?
Q1. How to detect enabling/disabling the watchdog timer through WDI pin?
Q2. When disabling the watchdog timer with floating WDI pin, will reset trigger accidentally…
Part Number: TPS3610 Hello,
I am looking for design guidelines using TPS3610U18PWR in Battery Backup Supervisor mode for RAM retention application. To be more specific what should be the status of all the pins in this mode. Also should the VBAT input…
You are correct that the TPS3610 is not designed to power the system in active mode through the battery backup switch. It is only designed to power the memory in standby mode.
Hi Pavaman,
Is VDD also 3.3V? Can you provide a schematic of your configuration?
If WDI pin is floating or high impedance, the device will generate its own watchdog pulse, but the device will not reset in this case. The behavior you described sounds…
Hi Kai,
The battery freshness seal feature is offered in some of our products disconnects the backup-battery from internal circuitry until it is needed, preventing the backup-battery from being discharged until the final product is put to use. This…
Hi CM,
Devices with BFS are : TPS3600, TPS3606, TPS3610, TPS3617 & TPS3619. Note, the TPS3600 and TPS3610 does not have timing requirements to enter BFS mode.

Thanks for the response.
When I was going through http://www.ti.com/lit/sg/sszb130b/sszb130b.pdf this document & I found recommended part as TPD8E003.
So now I'm in confusion to use any one of them, Can you please suggest me , which…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
