TPL5111: TPL5111

Blindu Marcel
Intellectual 325 points
Part Number: TPL5111


Hello,

I want to design a circuit to turn on/off power of microcontroller using a momentary button.The idea is to use the button as a power switch.

The logic is the following: Push the Button -> Turn on power of microcontroller, Press the button again -> turn off power of microcontroller, etc...

Can I use TPL5111 to turn on/off power using momentary button?

Best regards

    Hi Blindu,

    The TPL5111 is not suitable for this application since it power-cycles it's output pin. Momentarily asserting the DELAY/M_DRV with a pushbutton or switch will pull DRVn high but after the set time interval it will automatically return to low, turning the microcontroller back off.

    Regards,
