General Description
The MAX5938 is a hot-swap controller for -10V to -80V
rails. The MAX5938 allows circuit line cards to be safely
hot-plugged into a live backplane without causing a
glitch on the power supply. It integrates an adjustable
circuit-breaker function requiring no R
SENSE
.
The MAX5938 provides a controlled turn-on for circuit
cards, which limits inrush current and prevents both
glitches on the power-supply rail and damage to board
connectors and components. Before startup, the
MAX5938 performs a Load Probe" test to detect the
presence of a short-circuit condition. If a short-circuit
condition does not exist, the device limits the inrush cur-
rent drawn by the load by gradually turning on the exter-
nal MOSFET. Once the external MOSFET is fully
enhanced, the MAX5938 provides overcurrent and short-
circuit protection by monitoring the voltage drop across
the R
DS(ON)
of the external power MOSFET. The
MAX5938 integrates a 400mA fast GATE pulldown to
guarantee that the external MOSFET is rapidly turned off
in the event of an overcurrent or short-circuit condition.
The MAX5938 also protects the system against input
voltage (V
IN
) steps. During an input voltage step, the
device limits the current drawn by the load to a safe level
without shutting down the load. The device also includes
ON/OFF control, selectable PGOOD output polarity,
undervoltage (UV) and overvoltage (OV) protection.
The device offers latched (MAX5938L) or autoretry
(MAX5938A) fault management. Both the MAX5938A
and MAX5938L are available in a 16-pin QSOP package
and are specified for the extended (-40癈 to +85癈)
temperature range.
