EVALUATION KIT AVAILABLE  
MAX14691–MAX14693  
High-Accuracy, Adjustable Power Limiter  
General Description  
Benefits and Features  
Robust, High-Power Protection Reduces System  
The MAX14691–MAX14693 adjustable overvoltage,  
undervoltage, and overcurrent protection devices guard  
systems against overcurrent faults in addition to positive  
overvoltage and reverse-voltage faults. When used with  
an optional external pMOSFET, the devices also protect  
downstream circuitry from voltage faults up to +58V, -60V  
(for -60V external pFET rating). The devices feature a low,  
31mΩ, on-resistance integrated FET.  
Downtime  
• Wide Operating Input Range: +5.5V to +58V  
• -60V Negative Input Tolerance (for -60V External

• Thermal Foldback Current-Limit Protection  
• Dual-Stage Current Limiting  
- 1.0x Startup Current (MAX14691)  
- 1.5x Startup Current (MAX14692)  
- 2.0x Startup Current (MAX14693)  
Flexible Design Enables Reuse and Less  
Requalification  
During startup, the devices are 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. Additionally, the  
devices feature a dual-stage, current-limit mode in which  
the current is continuously limited to 1x, 1.5x, and 2x  
the programmed limit, respectively, for a short time after  
startup. This enables faster charging of large loads during  
startup.  
The MAX14691–MAX14693 also feature reverse-current  
and overtemperature protection. The devices are available  
in a 20-pin (5mm x 5mm) TQFN package and operate  
over the -40°C to 125°C temperature range.  
• Adjustable OVLO and UVLO Thresholds  
• Programmable Forward Current Limit From 0.6A
