AP2141D/AP2151D  
0.5A SINGLE CHANNEL CURRENT-LIMITED POWER  
SWITCH WITH OUTPUT DISCHARGE  
Application Note (Continued)  
Power Dissipation and Junction Temperature  
The low on-resistance of the internal MOSFET allows the small surface-mount packages to pass large current.  
Using the maximum operating ambient temperature (TA) and RDS(ON), the power dissipation can be calculated by:  
PD = RDS(ON)× I2  
Finally, calculate the junction temperature:  
TJ = PD x RθJA + TA  
Where:  
TA= Ambient temperature °C  
RθJA = Thermal resistance  
PD = Total power dissipation  
Generic Hot-Plug Applications  
In many applications it may be necessary to remove modules or pc boards while the main unit is still operating.  
These are considered hot-plug applications. Such implementations require the control of current surges seen by  
the main power supply and the card being inserted. The most effective way to control these surges is to limit and  
slowly ramp the current and voltage being applied to the card, similar to the way in which a power supply normally  
turns on. Due to the controlled rise times and fall times of the AP2141D/AP2151D, these devices can be used to  
provide a softer start-up to devices being hot-plugged into a powered system. The UVLO feature of the  
AP2141D/AP2151D also ensures that the switch is off after the card has been removed, and that the switch is off  
during the next insertion.  
By placing the AP2141D/AP2151D between the VCC input and the rest of the circuitry, the input power reaches  
these devices first after insertion. The typical rise time of the switch is approximately 1ms, providing a slow  
voltage ramp at the output of the device. This implementation controls system surge current and provides a hot-  
plugging mechanism for any device.
