The ADM1191-2ARMZ-R7 is an integrated Current Sense Amplifier 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 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 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.

• Precision voltage input
• Convert (CONV) pin for commanding an ADC read
• SETV input for setting overcurrent alert threshold
• ALERTB output provides an overcurrent interrupt
• I2C Fast mode-compliant interface (400kHz maximum)
• 2 Address pins allow 16 devices on the same bus
• 12-bit ADC for current and voltage readback
• 150°C Junction temperature
