ADBMS6817WCSWZ Description

Short technical summary and product information.

The ADBMS6817WCSWZ from Analog Devices is an 8-channel multicell battery stack monitor designed for monitoring up to 8 series-connected battery cells. It offers a maximum lifetime total measurement error of 1.5 mV and supports a cell measurement range from 0 V to 5 V, making it suitable for various battery chemistries.

 

This IC features a built-in isoSPI interface for isolated serial communications up to 20 meters, providing low EMI susceptibility and emissions. It supports bidirectional communication for broken wire protection and is hot-plug tolerant. The ADBMS6817WCSWZ includes a 16-bit ADC with a programmable noise filter, passive cell balancing up to 300 mA per channel, and 7 GPIO or analog inputs.

 

Designed for high-voltage battery packs, its stackable architecture allows for monitoring long battery strings. The ADBMS6817WCSWZ is AEC-Q100 qualified for automotive applications and models are developed for ISO 26262 applications with Automotive Safety Integrity Level Capability D (ASIL D).

 

The device is available in a 48-lead LQFP package with an exposed pad, suitable for surface mounting. Its sleep state supply current is a low 5.5 μA.
