Overview
The ADBMS18181 is a multicell battery stack monitor that measures up to 18 series connected battery cells with a total measurement error (TME) of less than 3.0 mV. The cell measurement range of 0 V to 5 V makes the ADBMS1818 suitable for most battery chemistries. All 18 cells can be measured in 290 µs, and lower data acquisition rates can be selected for high noise reduction. Multiple ADBMS1818 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each ADBMS1818 has an isoSPI interface for high speed, RF immune, long distance communications. Multiple devices are connected in a daisy chain with one host processor connection for all devices. This daisy chain can be operated bidirectionally, ensuring communication integrity, even in the event of a fault along the communication path. The ADBMS1818 can be powered directly from the battery stack or from an isolated supply. The ADBMS1818 includes passive balancing for each cell, with individual pulse-width modulation (PWM) duty cycle control for each cell. Other features include an on-board 5 V regulator, nine general-purpose I/O lines, and a sleep mode, where current consumption is reduced to 6 µA.
