PARAMETER TEST CONDITIONS MIN TYP MAX UNIT

(10) Common mode minimum aligns to VBUS UVLO. VBUS must be above its UVLO for the OCP function to be active.

(11) When T

trips a hard reset is transmitted and discharge is disabled, but the bleed discharge is not disabled.

(12) T

trips only when some external heat source drives the temperature up. When it trips the DVDD, and VAUX power outputs are turned

off.
