ADBMS6815 Description

The ADBMS6815 is a multicell battery stack monitor that measures up to 12 series connected battery cells with a lifetime total measurement error (TME) of less than 1.5 mV. The cell measurement range of 0 V to 5 V makes the ADBMS6815 suitable for most battery chemistries. All 12 cells can be measured in 304 µs, and lower data acquisition rates can be selected for high noise reduction.

Multiple ADBMS6815 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. Each ADBMS6815 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 ADBMS6815 can be powered directly from the battery stack or from an isolated supply. The ADBMS6815 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, seven general purpose input/output (GPIO) lines, and a sleep state, where current consumption is reduced to 5.5 µA.

The ADBMS6815WFS models are designed for use in ISO 26262 applications for Automotive Safety Integrity Level Capability D (ASIL D).
