Original question:

TCAN1043-Q1: Does it work well to set EN=NSTB=H before VCC=5V?

TCAN1043-Q1: TCAN1043

Part Number: TCAN1043-Q1

Tool/software:

1.What is the optimul value to pull up resistors on nstb an EN pins?

I hv used 10k pull up with MCU controlling both the pins

While wake up we pull them up additional through MCU

While going to Sleep we pull down nSTB pin..which mode it will be in and what will be INH pin status

Is it correct

    Chetan,

    10k is what we typically recommend for pull-up/pull-down resistor values on TCAN1043-Q1, but anything stronger than the internal pull-ups will work. They range from 275k to 2M ohms.

    Using the MCU to control these pins along with the pull-up resistors is the recommended operation. Pulling nSTB down while EN is high will place the device into Sleep mode, and INH will be in the low state.
