DESCRIPTION (CONTINUED)
During initial turnon of the switch (inrush mode), an external resistor is used to program the inrush current, allowing a wide
range of capacitor values to be used at the load. According to IEEE 802.3af specification, inrush current of 400 mA is
allowed only for 50 ms, limiting the load capacitor to approximately 180
F. A programmable inrush current limit removes
this limitation, allowing a larger capacitor to be used with a lower inrush current limit.
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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
