DATA SHEET  
AAT4616: Ultrahigh Precision Adjustable Current Limited  
Load Switch with Fault Flag  
Applications  
Description  
The AAT4616 SmartSwitch is a current-limit P-channel MOSFET  
power switch designed for high-side load switching applications.  
This switch operates with inputs ranging from 2.4 V to 5.5 V,  
making it ideal for both 3 V and 5 V systems. An integrated, highly  
accurate current-limit circuit protects the input supply against  
large currents, which may cause the supply to fall out of  
regulation. Reverse current blocking is provided to protect the  
load switch from reverse current flows while the device is in  
shutdown.

Features  
The AAT4616 is also protected from thermal overload, which  
limits power dissipation and junction temperature. Current-limit  
threshold is programmed with a resistor from SET to ground, and  
is adjusted for load levels up to 1.6 A. The ultrafast current limit  
response to a sudden short circuit is 2 s, which reduces the  
requirements of local supply bypassing. An open-drain FAULT flag  
signals an over-current or over-temperature condition. To prevent  
false reporting, a 4 ms time interval is used at startup (charging a  
capacitive load), where fault conditions are not monitored and  
reported. Quiescent current is a low 10 A and the supply current  
decreases to less than 1 A in shutdown mode.  
Input voltage: 2.4 V to 5.5 V

The AAT4616 is offered in small Pb-free, 5-pin SOT23-5 and  
TDFN22-8 packages, and is specified for operation over the  
–40°C to +85°C ambient temperature range.  
A typical application circuit is shown in Figure 1. The pin  
configuration is shown in Figure 2. Signal pin assignments and  
functional pin descriptions are provided in Table 1.
