Part Number: SN74AUP3G14 Other Parts Discussed in Thread: TPS3421 Hi Team，
Could you please help me with below issue? “TPS3421+SN74AUP3G14” is used in the system to reset the MCU, where SN74AUP3G14 is used to flip the reset signal. The input side of…
Part Number: TPS3422 Other Parts Discussed in Thread: TPS3421 The part which label shows TPS3422EGDRYT, but after decapsulation it marks TPS3421, pls help to confirm the difference, thx.
Other Parts Discussed in Thread: TPS3421 , TPS3899 Hi Team,
Do we have a device could compete the SR1UARU, which is STMicroelectronics Voltage Supervisory.
but I do not find suitable device in Ti.com.
Could you give me some suggestions, thanks…
Hi user,
The TPS3420 has NMOS based inputs that do not require pullup resistors. For that configuration, I recommend using the TPS3421.
Thanks, Abhinav.
Hi Kevin,
We have fixed timing push-button devices (TPS3420, TPS3421, TPS3422) and also we have content that shows how to create programmable push-button devices using our voltage supervisors. Please email me directly at michaeldesando@ti.com so we…
Hi NT,
I am not sure the TPS3421 results in the desired operation. Reading the datasheet, it appears both pushbuttons must be pressed for many seconds before a reset pulse is issued.
Is that what you want? If not, the TPS3421 may have to be replaced…

I saw a preview part TPS3421A.
Would you be able to share what is the main different between this A version and the original.
I have a customer looking for a TPS3421 with 15 sec t_timer…
Tapas,
Yes, any of our push-button controllers will be excellent for this application. This includes our single button controller TPS3422 and our dual button controllers TPS3420 and TPS3421. Also, if you need extra flexibility (specific reset delay…
Shlomi,
We do not currently have a device identical to LTC2954. We have pushbutton controllers: TPS3420, TPS3421, and TPS3422. These devices require a button press for certain duration of time before the output resets. The output can either reset…
Jeff,
Schematic: EN1 is high, EN2 is low.
Unfortunately we have an embedded system and we can read the charger's register only when we connect our device to a debug adapter. Moreover I have got no defect device until now. Our customer got 2 devices…
