GENERAL DESCRIPTION
The ADM1191 is an integrated current sense amplifier that
3.15V TO 26V
R SENSE
offers digital current and voltage monitoring via an on-chip
12-bit analog-to-digital converter (ADC), communicated
through an I 2 C? interface.

P = VI
An internal current sense amplifier measures 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 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 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 I 2 C 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 with the output voltage on the current
sense amplifier. The output of the SETV comparator asserts
when the current sense amplifier output exceeds the SETV
voltage. When this event occurs, the ALERTB output asserts.

Figure 2. Applications Diagram
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.
