Q: TPS65030 TEST SRP by 1627563

Hi,

 

This is regarding the Power management IC for USB - TPS65030. I am not going to use the Test SRP function so can i leave the pin floating for this?

 

Regards,

When not in test mode, the TEST SRP pin (open drain) sets the start-up current limit for the charge pump, Vbus. If Test SRP is pulled high, the Vbus current during startup is > 100 mA. If pulled low, it is 1 mA. TEST SRP should be pulled high or low.
