AP22652/AP22653/AP22652A/AP22653A  
PRECISION ADJUSTABLE CURRENT-LIMITED POWER SWITCHES  
Description  
Pin Assignments  
The AP22652, AP22653, AP22652A, and AP22653A are single-  
channel, precision-adjustable, current-limited switches optimized for  
applications that require precision current limiting, or to provide up to  
2.1A of continuous load current during heavy loads/short circuits.  
These devices offer a programmable current-limit threshold between  
125mA and 2665mA (typ) via an external resistor. Current-limit  
accuracy ±10% can be achieved at high current-limit settings. The  
rise and fall times are controlled to minimize current surges during  
turn on/off.

W-DFN2020-6 (Type A1)  
(Top View)  
The devices have fast short-circuit response time for improved overall  
system robustness. They provide a complete protection solution for  
applications subject to heavy capacitive loads and the prospect of  
short circuit, offering reverse-current blocking and limiting,  
overcurrent, overtemperature, and short-circuit protection, as well as  
controlled rise time and undervoltage lockout functionality. A 6ms  
deglitch capability on the open-drain flag output prevents false  
overcurrent reporting and does not require any external components.

The AP22652 and AP22653 limit the output current to a safe level  
when the output current exceeds current-limit threshold.
