General Description
The MAX5900/MAX5901 are SOT23 hot-swap controllers
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 MOSFET’s 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 packages, and
are specified for the extended -40°C to +85°C tempera-
ture range. For specific ordering information see the
Selector Guide
at the end of the data sheet.
