TPS659037: Interrupt source and mask for INT3

Takeshi Sasaki

Part Number: TPS659037

Hi team,

Can the customer mask Vbus as shown in datasheet p54, at Table 5-6? The user's guide and technical reference manual don't show whether Vbus can be masked or not. Thank you for your support.

Best regards,

Sasaki-san,

The VBUS interrupt settings cannot be changed. If you are not using VBUS, you can ground this pin.

Thanks,

Hi Nastasha,

Thank you for your comment. The customer wants to use Vbus, and to implement GPIO_1 as detection of Vbus. To confirm, is Vbus really interrupt source at INT3 as shown in Table 5-6 at the datasheet? If not, it is ok to the customer in that case. But, if yes, they want to mask Vbus interrupt.

Best regards,

Takeshi Sasaki

Sasaki-san,

In looking deeper into the OTP configuration, the VBUS interrupt is part of INT3. However, it is disabled by default.

Thanks,
Nastasha
