(1) If TJ1 is perceived to have been exceeded an OTSD occurs and the discharge FET is disabled.
(2) The discharge pull-down is not active in the sleep mode.
(3) When voltage on the PCTRL pin is less than V(PCTRL_TH), the amount of power advertised is reduced by half.
(4) Leaving HIPWR or PSEL open is an undetermined state and leads to unpredictable behavior.
(5) These pins are high-z during a UVLO, reset, or in Sleep condition.
(6) The pins were designed for less leakage, but testing only verifies that the leakage does not exceed 0.5 µA.
(7) Standard Rp mode is active after a USB Type-C sink, debug accessory, or audio accessory is attached until the first USB PD message is transmitted (after GDNG has been enabled).
(8) 1.5 A Rp mode is active after a USB PD message is received.
(9) 3 A Rp mode is active after GDNG has been enabled until a USB PD message is received.
(10) VWAKE < VOCDS is always true.
(11) Common mode minimum aligns to VBUS UVLO. VBUS must be above its UVLO for the OCP function to be active.
(12) When TJ1 trips a hard reset is transmitted and discharge is disabled, but the bleed discharge is not disabled.
(13) TJ2 trips only when some external heat source drives the temperature up. When it trips the DVDD, and VAUX power outputs are turned off.
