What this part is and what it does
The MAX17215G+00E is a multi-function battery fuel-gauge controller from Maxim Integrated's ModelGauge™ series. It communicates over a 1-Wire interface, which means a single data line plus ground carries both power and bidirectional data to the host microcontroller — handy when you're short on GPIO or running a remote battery pack over a twisted pair. The part manages 2 to 3 series lithium-based cells, so it fits 2S or 3S battery packs typical in portable instruments, power tools, or backup battery units.
Lifecycle and sourcing posture
The MAX17215G+00E is listed as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so it's suitable for both new designs and production replenishment. Sourced through independent distribution; pricing and availability are confirmed at quote time.
