EVALUATION KIT AVAILABLE  
MAX17525  
High-Accuracy, Adjustable Power Limiter  
General Description  
Benefits and Features  
Robust, High-Power Protection Reduces System  
The MAX17525 adjustable overvoltage, undervoltage,  
and overcurrent protection device guards systems against  
overcurrent faults in addition to positive overvoltage and  
reverse-voltage faults. When used with an optional external  
pMOSFET, the device also protects downstream circuitry  
Downtime  
• Wide Input-Supply Range: +5.5V to +60V  
• Programmable Input-Supply Overvoltage Setting  
Up To 40V  
• -60V Negative Input Tolerance with External

on-resistance integrated FET.

• Reverse Current-Blocking Protection with External  
pFET  
During startup, the MAX17525 is designed to charge  
large capacitances on the output in a continuous mode  
for applications where large reservoir capacitors are used  
on the inputs to downstream devices. Two additional part  
options that feature a dual-stage, current-limit mode in  
which the current is continuously limited to 1.5x and 2x  
the programmed limit are available upon request. These  
options enable faster charging of large load capacitances  
during startup.  
The MAX17525 also features reverse-current and  
overtemperature protection. The device is available in a  
20-pin (5mm x 5mm) TQFN package and operate over  
the -40ºC to 125ºC temperature range.
