Hi,all

Is there any product from TI such as LTC2955ITS8-1 about pushbutton on/off controller? must be low supply current(below 1.5uA), and supply range is 1.7V to 3.7V.

I will use a DRV5032 instead of a key switch about pushbutton.

thanks! Look forward to your reply.

Hi,Parekh!

Thank your reply! but sorry, TPS3422 can not meet my needs. I need a power supply pushbutton controller, rather than a reset pushbutton controller. due to reset controller can not lock the EN of TPS62740 or other converter when the pushbutton is pressed.

regards!

Hi Wang,

From my understanding, you are looking for a push button solution with a latching feature?
We current do not have that integrated in one device.
Are you open to external components to add in a discrete latching?
