AP2145/AP2155  
0.5A SINGLE CHANNEL CURRENT-LIMITED POWER  
SWITCH WITH OUTPUT DISCHARGE  
Description  
Pin Assignments  
The AP2145 and AP2155 are integrated high-side power  
switches optimized for Universal Serial Bus (USB) and other  
hot-swap applications. The family of devices complies with  
USB 2.0 and available with both polarities of Enable input.  
They offer current and thermal limiting and short circuit  
protection as well as controlled rise time and under-voltage  
lockout functionality. A 7ms deglitch capability on the  
open-drain Flag output prevents false over-current reporting  
and does not require any external components.
