PRODUCT DATASHEET  
AAT4684  
OVPSwitchTM  
Over-Voltage Protection Switch  
General Description  
Features  
The AAT4684 OVPSwitch™ is a member of AnalogicTech’s  
Application Specific Power MOSFET™ (ASPM™) product  
family. It is a P-channel MOSFET power switch with pre-  
cise over-voltage protection control, designed to protect  
low-voltage systems against high-voltage faults up to  
+28V. If the input voltage exceeds the programmed  
over-voltage threshold, the P-channel MOSFET switch  
will be turned off to prevent damage to the output load  
circuits. The AAT4684 is available with an internally pro-  
grammed over-voltage trip point or as an adjustable  
version programmed by two external resistors.  
• Over-Voltage Protection Up to +28V  
• Fixed or Adjustable Over-Voltage Protection Threshold  
• 3V Under-Voltage Lockout Threshold  
• Fast OVP Response:  
1μs (Max) to Over-Voltage Transient  
• Low Operation Quiescent Current  
30μA Typical  
1μA Max in Shutdown (Disabled)  
• 100mΩ Typical (130mΩ max) RDS(ON) at 4.5V  
• 1.8A Maximum Continuous Current  
Temperature Range: -40°C to 85°C  
• Available in TSOPJW-12 Package  
The AAT4684 also includes an under-voltage lockout  
(UVLO) protection circuit, which will put the device into  
sleep mode at low input voltages only consuming < 1μA  
of current.  
Applications  
• Cell Phones  
The AAT4684 is offered in a small Pb-free, 12-pin  
TSOPJW package and is specified for operation over the  
-40°C to +85°C ambient temperature range.  
• Digital Still Cameras  
• GPS  
• MP3 Players  
• Personal Data Assistants (PDAs)  
• USB Hot Swap/Live Insertion Device
