Note 1: Power dissipation is 825 mW when mounted. Derate at 6.6 mW/°C for operation above 25°C.
Note 2: Conditions for "wake-up": either 1) VIN exceeds VIN(H), stays above VIN(L), and VCC passes VCC(ON)
or 2) VCC exceeds VCC(ON), stays above VCC(OFF), and VIN exceeds VIN(H).
Conditions for "standby": either 1) VCC never exceeds VCC(ON)
or 2) VCC drops below VCC(OFF)
or 3) VIN never exceeds VIN(H).
Note 3: Guaranteed by design; not 100% tested.
