Part Number: TPS3606-33 Hello There,
I am using Power Fail Comparator Feature of TPS3606-33. I am monitoring 5V with Resistor divider of R1 = 1.664MOhms & R2 = 664kOhms. So VPFI = 5V * R2 / (R1+R2)=1.426V.
Whenever 5V drops below 4V system thresold…
Part Number: TPS3606-33 Hello,
I am using the TPS3606-33 part in a battery powered embedded design. The schematic for the design involving the TPS3606-33 part is shown below.
For this design the VBAT pin is driven from the output of a 3.3V regulator U4…
Part Number: TPS3606-33 Other Parts Discussed in Thread: TPS3600 , TPS3610 Dear,
I am using TPS3606 and i have observed that when the WDI pin is pulled high to 3.3V , at this point the WDI had voltage pulsating from 3.3V to 3.15 (ON-OFF-ON state) and the…
Part Number: TPS3606-33 We are using the TPS3606-33 part. The input is the Aux supply which provides VDD = 3.3V & we have battery backup of VBAT = 3.6V.
What we have observed is that; if VBAT is low <1.5V, and if VDD of 3.3V is applied, sometimes…
Hi Michael,
I agree with your suggestion and usage of the PFI and PFO pins along with Mswitch to try and achieve a switch over voltage closer to ~3.2V for the TPS3606-33 part. Luckily the design I am working with does use the PFI and PFO pins along with…
