MAX5900LBEUT+T

P1-P3P4-P6P7-P9P10-P12P13-P14
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 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 and TDFN pack-
ages, and are specified for the extended -40°C to +85°C
temperature range. For specific ordering information see
the Selector Guide at the end of the data sheet.

Note 1: All currents into device pins are positive, all currents out of device pins are negative, and all voltages are referenced to
GND, unless otherwise noted.
Note 2: All specifications are 100% tested at T
A
= +25°C. Specifications over -40°C to +85°C are guaranteed by characterization.
Note 3: This is the delay time from a valid on condition until V
GS
begins rising. Valid on conditions are: the device is not in undervolt-
age lockout; ON/OFF is not driven low; and the device is not in thermal shutdown.
Note 4: This is the delay from a valid low on ON/OFF until V
GS
falls. Pulses on ON/OFF less than t
OFF
are ignored, offering glitch
immunity.
Note 5: Guaranteed by design, not production tested.
Note 6: For a detailed description, see the Power-Good Output section.
