General Description
The MAX5936/MAX5937 are hot-swap controllers for
-10V to -80V rails. The MAX5936/MAX5937 allow circuit
line cards to be safely hot-plugged into a live back-
plane without causing a glitch on the power supply.
These devices integrate a circuit-breaker function
requiring no R
SENSE
.
The MAX5936/MAX5937 provide a controlled turn-on
for circuit cards, limiting inrush, preventing glitches on
the power-supply rail, and preventing damage to board
connectors and components. Before startup, the
devices perform 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
current drawn by the load by gradually turning on the
external MOSFET. Once the external MOSFET is fully
enhanced, the MAX5936/MAX5937 provides overcur-
rent and short-circuit protection by monitoring the volt-
age drop across the R
DS(ON)
of the external power
MOSFET. The MAX5936/MAX5937 integrate a 400mA
fast GATE pulldown to guarantee that the power
MOSFET is rapidly turned off in the event of an overcur-
rent or short-circuit condition.
The MAX5936/MAX5937 protect the system against
input voltage (V
IN
) steps by providing V
IN
step immuni-
ty. The MAX5936/MAX5937 provide an accurate UVLO
voltage. The MAX5936 has an open-drain, active-low
PGOOD output and the MAX5937 has an open-drain,
active-high PGOOD output.
The MAX5936/MAX5937 are offered with 100mV,
200mV, and 400mV circuit-breaker thresholds, in addi-
tion to a non-circuit-breaker option. These devices are
offered in latched and autoretry fault management, are
available in 8-pin SO packages, and specified for the
extended (-40癈 to +85癈) temperature range (see the
Selector Guide).
