Battery pack voltage monitor

Hi,

any know of a IC that can monitor a single battey voltage, ideally with I2C or SPI interface, Ideally I want a small IC that has an interface so I can read the voltage from it, I want to have several of hese so I can monitor a battery pack in series.

Thx

what you want is a I²C Analog to digital converter...
go to semiconductor manufacturers site's and search for AD converters...

Have a look at my PIC tutorials, in the I2C tutorial I use an I2C A2D chip, this has a number of different analogue inputs.

What processor are you using?, you can get most types with A2D built in.
