General Description
The MAX5900/MAX5901 are SOT23/TDFN hot-swap con-
trollers that allow a circuit card to be safely hot-plugged
into a live backplane without causing a glitch on
the power-supply rail. These devices operate from -9V to
-100V and provide the simplest hot-swap solution by
eliminating all external components except an external
n-channel MOSFET.
The MAX5900/MAX5901 limit the inrush current to the
load and provide a circuit-breaker function for overcurrent
protection. During startup, the circuit-breaker function is
disabled and the MAX5900/MAX5901 limit the inrush cur-
rent by gradually turning on the external MOSFET. Once
the external MOSFET is fully enhanced, the circuit-break-
er function is enabled and the MAX5900/MAX5901 pro-
vide overcurrent protection by monitoring the voltage
drop across the external MOSFETs on-resistance.
The MAX5900/MAX5901 include an undervoltage lock-
out (UVLO) function, ON/OFF control input, and a power-
good status output, PGOOD (MAX5900) or PGOOD
(MAX5901). A built-in thermal shutdown feature is also
included to protect the external MOSFET in case of over-
heating.
The MAX5900/MAX5901 offer latched or autoretry fault
management and are available with 200mV, 300mV, or
400mV circuit-breaker thresholds. Both the MAX5900 and
MAX5901 are available in small SOT23 and TDFN pack-
ages, and are specified for the extended -40癈 to +85癈
temperature range. For specific ordering information see
the Selector Guide at the end of the data sheet.
