GENERAL DESCRIPTION
The ADM1177 is an integrated hot-swap controller which offers
digital current and voltage monitoring via an on-chip 12-bit
ADC, communicated through an I2C interface.
An internal current sense amplifier senses voltage across the
sense resistor in the power path via the VCC and SENSE pins.
The ADM1177 limits the current through this resistor by
controlling the gate voltage of an external N-channel FET in the
power path, via the GATE pin. The sense voltage (and hence the
inrush current) is kept below a preset maximum.
The ADM1177 protects the external FET by limiting the time
that it spends with the maximum current running in it. This
current limit period is set by the choice of capacitor attached to
the TIMER pin. Additionally, the device provides protection
from overcurrent events at times after the hot-swap event is
complete. In the case of a short-circuit event the current in the
sense resistor will exceed an overcurrent trip threshold, and the
FET will be switched off immediately by pulling down the
GATE pin.

A Soft-start (SS) pin is also included. This gives the user control
over the reference on the current sense amplifier. An internal
current source will charge a capacitor on this pin at startup,
allowing the user set the profile of the initial current ramp. A
voltage can also be driven on this pin to alter the reference.
A 12-bit ADC can measure the current seen in the sense
resistor, and also the supply voltage on the VCC pin.
An industry standard I2C interface allows a controller to read
current and voltage data from the ADC. Measurements can be
initiated by an I2C command. Alternatively the ADC can run
continuously and the user can read the latest conversion data
whenever it is required. Up to 4 unique I2C addresses can be
created by the way the ADR pin is connected.
The ADM1177 is packaged in a 10-lead MSOP package.
