GENERAL DESCRIPTION
The ADM1191 is an integrated current sense amplifier that
offers digital current and voltage monitoring via an on-chip,
12-bit analog-to-digital converter (ADC), communicated
through an I2C interface.
An internal current sense amplifier senses voltage across the sense
resistor in the power path via the VCC pin and the SENSE pin.
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 I2C interface allows a controller to read
current and voltage data from the ADC. Measurements can be
initiated by an I2C command or via the convert (CONV) pin.
The CONV pin is especially useful for synchronizing reads on
multiple ADM1191 devices. Alternatively, the ADC can run
continuously, and the user can read the latest conversion data
whenever it is required. Up to 16 unique I2C addresses can be
created, depending on the way the A0 pin and the A1 pin are
connected.
A SETV pin is also included. A voltage applied to this pin is
internally compared to the output voltage on the current sense
amplifier. The output of the SETV comparator asserts when the
current sense amplifier ouput exceeds the SETV voltage. When
this event occurs, the ALERTB output asserts.

The ALERTB output can be used as a flag to warn a micro-
controller or field programmable gate array (FPGA) of an
overcurrent condition. ALERTB outputs of multiple ADM1191
devices can be tied together and used as a combined alert.
The ADM1191 is packaged in a 10-lead MSOP.
