2V, n-Channel Hot-Swap Controllers Require No Sense Resistor General Description 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 voltage, VCC, is at or above 2.
25V and the hotswapped supply, VS, does not exceed VCC.
The MAX5924/MAX5925/MAX5926 hot-swap controllers limit the inrush current to the load and provide a circuitbreaker 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 MAX5924/MAX5925/MAX5926 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 n-channel MOSFET.
The MAX5924/MAX5925/MAX5926 are available with open-drain PGOOD and/or PGOOD outputs.
The MAX5925/MAX5926 also feature a circuit breaker with temperature-compensated R DS(ON) sensing.
The 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 faultmanagement configurations are available (see the Selector Guide).
