Section 1.1, "Configurable

Features," on page 4

Updated bulleted lists. USB signal drive strength,

USB differential pair pin location and downstream

port power control / over-current detection items

moved from first (strap-configurable) bulleted list to

the second (EEPROM-configurable) bulleted list.

Added enabling of battery charging to the first

bulleted list.

Section 3.1, "Pin

Table 3-2, “USB251xB/xBi Pin

Descriptions,” on page 12

Updated VBUS_DET buffer type to “I” and changed

description to: “For self-powered applications with a

permanently attached host, this pin must be

connected to a dedicated host control output, or

connected to the 3.3 V domain that powers the

host (typically VDD33).”
