PIN DESCRIPTION
Pin
Name
Function
Number
Power input of the PFET switch. It also provides power to the entire IC. Connect to the voltage rail that the
VCC
A1
accessory device is expected to work off.
GND
B1
Common Ground (device substrate).
POK
C1
Open-drain PFET status indicator. When the PFET is off, this pin floats. When PFET is on, it is grounded.
ACC_DET
C2
Pull this pin low to tell the IC that the downstream accessory device is plugged in.
When this pin is low, the PFET will be turned off and POK will be open-drained. Current limit circuitry will also
ENABLE
B2
be disabled. The IC will be in a low-power state. This pin should be held low until VCC is established to
ensure proper initial state of internal logic. When ENABLE is high, the PFET switch will be allowed to turn on.
ACC_PWR
A2
Power output terminal of the PFET switch. Connect to input rail of accessory device.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
Absolute Maximum Ratings

VCC
-0.3V to 6V
ENABLE, POK, ACC_DET,
ACC_PWR(2)
-0.3V to 6V
Junction Temperature (TJ)

Storage Temperature Range
−65°C to +150°C
ESD Susceptibility, Human Body Model(3)
2kV
(1)
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which
operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and
associated test conditions, see the Electrical Characteristics table.
(2)
The voltages on these pins should never exceed VCC+0.3V.
(3)
The human body model is a 100pF capacitor discharged through a 1.5 k
Ω resistor into each pin. Test method is per JESD-22-A114.
