Device identity and BOM-fit
The BQ34Z653DBT is an SBS 1.1-compliant fuel gauge IC from Texas Instruments, designed to report battery state-of-charge, voltage, current, and temperature over the SMBus interface.
Package and inventory handling
Supplied in Bulk packaging — no reel or tape carrier, so the reels don't need dry-storage management, but the loose ICs should be kept in ESD-safe bins with the original moisture-barrier bag if resealing is required. The part sits in the Analog & Data Acquisition category, which covers battery management front-ends like this gauge — a signal-chain component, not a power-stage device.
