1V to 13.2V, n-Channel Hot-Swap Controllers  
Require No Sense Resistor  
General Description  
Benefits and Features  
● Hot Swap 1V to 13.2V with V  
The MAX5924/MAX5925/MAX5926 1V to 13.2V hot-swap  
controllers allow the safe insertion and removal of circuit  
cards into live backplanes. These devices hot swap supplies  
ranging from 1V to 13.2V provided that the device supply  
≥ 2.25V

supply, V , does not exceed V

● Protected During Turn-On into Shorted Load  
● Adjustable Circuit-Breaker Threshold  
● Programmable Slew-Rate Control  
● Programmable Turn-On Voltage  
The MAX5924/MAX5925/MAX5926 hot-swap controllers  
limit the inrush current to the load and provide a circuit-  
breaker function for overcurrent protection. The devices  
operate with or without a sense resistor. When operating  
without a sense resistor, load-probing circuitry ensures a  
short circuit is not present during startup, then gradually  
turns on the external MOSFET. After the load probing  
is complete, on-chip comparators provide overcurrent  
protection by monitoring the voltage drop across the  
external MOSFET on-resistance. In the event of a fault  
condition, the load is disconnected.

The devices include many integrated features that reduce  
component count and design time, including configurable  
turn-on voltage, slew rate, and circuit-breaker threshold. An  
on-board charge pump provides the gate drive for a low-  
cost, external nMOSFET.

DS(ON)  
MAX5926 features a selectable 0ppm/°C or 3300ppm/°C  
temperature coefficient. The MAX5924 temperature  
coefficient is 0ppm/°C and the MAX5925 temperature  
coefficient is 3300ppm/°C. Autoretry and latched fault-  
management configurations are available (see the  
Selector Guide).
