Using TPS3801I50DCK for 3-microcontroller supervisory

Other Parts Discussed in Thread: TPS3801

Hi,

I want to use the TPS3801I50DCK to act as a supervisory for a 5V microcontroller and I have a couple of doubts:

1) Is this IC (TPS3801I50DCK) going to be discontinued?

2) Can I use one of the TPS3801I50DCK to control 3 microcontrollers? or should I use one TPS3801I50DCK for each microcontroller (3 TPS3801I50DCK)?

Thanks and regards.

    Hi Carlos,

    1) No, there is currently no plan to discontinue the 5V version of the TPS3801

    2) You can use one supervisor to drive the RESET of the 3 microcontrollers as long as the overall output current of the TPS3801 creates the appropriate VOL and VOH for the microcontrollers. Please see Figures 3,5, and 6 of the datasheet.

    Regards,
