General Description
The MAX5900/MAX5901 are SOT23 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 overcur-
rent protection. During startup the circuit breaker func-
tion is disabled and the MAX5900/MAX5901 limit the
inrush current by gradually turning on the external
MOSFET. Once the external MOSFET is fully enhanced,
the circuit breaker function is enabled and the
MAX5900/MAX5901 provide overcurrent protection by
monitoring the voltage drop across the external MOS-
FET’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 fea-
ture is also included to protect the external MOSFET in
case of overheating.
The MAX5900/MAX5901 offer latched or auto-retry 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 tem-
perature range. For specific ordering information refer
to the
Selector Guide
at the end of the data sheet.
