GENERAL DESCRIPTION
The ADM1175 is an integrated hot swap controller and current
sense amplifier that offers digital current and voltage monitoring

communicated through an I 2 C? interface.
An internal current sense amplifier measures voltage across
the sense resistor in the power path via the VCC pin and the
SENSE pin.
The ADM1175 limits the current through this resistor by
controlling the gate voltage (via the GATE pin) of an external
N-channel FET in the power path. The voltage across the sense
resistor (and, therefore, the inrush current) is kept below a
preset maximum.
The ADM1175 protects the external FET by limiting the time
that the maximum current runs through it. This current limit
period is set by the value of the capacitor attached to the TIMER
pin. Additionally, the device provides protection from overcurrent
events that may occur once the hot swap event is complete. In
the case of a short-circuit event, the current in the sense resistor
exceeds an overcurrent trip threshold, and the FET is switched
off immediately by pulling down the GATE pin.

Figure 2. Applications Diagram
A 12-bit ADC can measure the current seen in the sense resistor,
as well as the supply voltage on the VCC pin. An industry-standard
I 2 C interface allows a controller to read current and voltage data
from the ADC. Measurements can be initiated by an I 2 C command
or via the convert (CONV) pin. The CONV pin is especially
useful for synchronizing reads on multiple ADM1175 devices.
Alternatively, the ADC can run continuously, and the user can
read the latest conversion data whenever it is required. Up to four
unique I 2 C addresses can be created, depending on how the ADR
pin is connected.
The ADM1175 is packaged in a 10-lead MSOP.
