SLLSE09J November 2009 – July 2021 TUSB1210
PRODUCTION DATA
VBUS, VBAT, and VDDIO are needed to power the TUSB1210. Recommended operation is for VBAT to be present before VDDIO. Applying VDDIO before VBAT to TUSB1210 is not recommended as there is a diode from VDDIO to VBAT which will be forward biased when VDDIO is present but VBAT is not present. TUSB1210 does not strictly require VBUS to function.
