PI5PD2560/2561  
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||  
Dual Channel, Adjustable Current -Limited Power Switch  
Features  
Description  
Two separate current limiting channels  
Meets USB Current-Limiting Requirement  
±7.5% Current-Limit Accuracy at 2.8A  
Adjustable Current Limit, 250mA-2.8A (typ)  
Fast Over-current Response - 3.5μS (typ)  
44mΩ High-Side MOSFET  
The PI5PD2560/2561 is dual-channel power-distribution  
switch intended for applications where precision current  
limiting is required or heavy capacitive loads and short  
circuits are encountered. These devices offer a  
programmable current-limit threshold between 250 mA  
and 2.8A (typ) per channel via an external resistor. The  
power-switch rise and fall times are controlled to  
minimize current surges during turn on/off.  
Operating Range: 2.5 V to 5.5V  
2μA Maximum Standby Supply Current  
Reverse Input-Output Voltage Protection  
Built-in Soft-Start  
Each channel of the PI5PD2560/2561 devices limit the  
output current to a safe level by switching into a  
constant-current mode when the output load exceeds the  
current-limit threshold.  
15 kV / 8 kV System-Level ESD Capable  
Device Package: TDFN 3x3-10L  
UL Listed – File No. E341484  
CB Certified  
The FAULTx logic output for each channel  
independently asserts low during over-current or over  
temperature.
