TUSB4041I-Q1: Operation at reset

Ryu Yamashita

Tool/software:

Hi team,

What are the states of PWRCTL1/BATEN1 and PWRCTL2/BATEN2 at reset?
Are they input or output respectively?
Could you please tell me how many ohms are pulled down and pulled up, respectively?

Best Regards,
Ryu.

Hi Ryu:

PWRCTL is output pin, the states of PWRCTL pin depend on PWRCTL_POL . it is used to control external Vbus switch.

No exteranl pu or pd needed unless you need to enable BATEN.

Hi Brian,

Does this mean that the output will be active high or active low depending on PWRCTL_POL when reset?
For the output, I assume there is an internal PU and PD.
Can you tell me the resistance value of each of these?

Best Regards,
Ryu.

correct.

internal PU and PD is for input , not for output.
