GENERAL DESCRIPTION
The ADM1171 is a hot swap controller that safely enables a
printed circuit board to be removed and inserted to a live
backplane. This is achieved using an external N-channel power
MOSFET with a current control loop that monitors the load
current through a sense resistor. An internal charge pump is
used to enhance the gate of the N-channel FET. When an
overcurrent condition is detected, the gate voltage of the FET is
reduced to limit the current flowing through the sense resistor.
During an overcurrent condition, the TIMER cap determines
the amount of time the FET remains at a current limiting mode
of operation until it is shut down. The ON (ON-CLR) pin is the
enable input for the device and can be used to monitor the
input supply voltage. The ADM1171 operates with a supply
voltage ranging from 2.7 V to 16.5 V.
The ADM1171 features soft start to provide the user with a
capacitor programmable ramping reference to the internal
current sense comparator. This provides a linearly increasing
current limit at startup at a rate set by C SS . This helps to reduce
and limit large inrush currents.
The ADM1171 also features a current sense output (CSOUT)
pin. The voltage on the CSOUT pin represents the voltage drop
across the sense resistor gained up by a factor of 20.
This device is available in two options: the ADM1171-1 with
automatic retry for overcurrent fault and the ADM1171-2 with
latch-off for an overcurrent fault. Toggling the ON (ON-CLR)
pin resets a latched fault. The ADM1171 is packaged in an
8-lead TSOT.
