Part Number: TPS3420 Other Parts Discussed in Thread: TPS3899 Hi team!
Using the TPS3420 as a reset pushbutton where a reset is performed by holding the power button for about 10s typically. Sometimes, there is very little current drawn on Vsys, so the…
Part Number: TPS3420 Hello, My circuit has an initial condition of PBx powered logic high and VCC floating. For above situation, I see potential appear on VCC. Could you comment if this is expected behavior? Thanks!
Part Number: TPS3420 Other Parts Discussed in Thread: TPS3421 Hello,
I'm looking at the differences between the TPS3420 and the TPS3421 and the primary difference seems to be the fixed RST on the TPS3421. With the TPS3420, what would it take to switch…
Part Number: TPS3420 Hi Team,
Regarding TPS3420, understand from the datasheet that this reset IC monitors 2 inputs when simultaneously held low and output an active-low reset pulse signal.
If we were to connect the 2 inputs together to a switch, which…
Part Number: TPS3421EGEVM-156 Other Parts Discussed in Thread: TPS3420 , TPS3421 , TPS3422 Per the TPS3421EGEVM-156 Evaluation Module manual, the evaluation module can be modified to evaluate the TPS3420 by removing R1 and R2, and shorting TS to GND. Based…
Part Number: TPS3420 Hello,
TPS3420DDRYR /RST pin keeps output LOW after system ESD test (15kV air discharge). PB1/PB2 are normal HIGH (connect10K resistor to VCC), TS connects to VCC.
It can recover to normal only after Power on reset.
Do you know how…

Can i use/do i need external pullups on PBx inputs on TPS3420 in case of active low button that is conneted on MCU as well. I need to have system VDD on PBx lines in case not pressed.
Part Number: TPS3420 Hi expert,
Customer is asking for solution which is similar like TPS3420 but will need to keep low or high status for output and toggle status to high or low at next pulse generated by push button. Do we have solution could support…
