It sits in a 14-TSSOP package, surface-mount, and covers an industrial temperature range of -40°C to 85°C. This part is suited for portable equipment, backup systems, and energy-storage applications where you need to track state-of-charge across lithium-ion, LiFePO4, or other chemistries without swapping the monitor. ## What the ratings mean for fit The multi-chemistry support is the headline feature — you can use this monitor with lithium-ion, lithium iron phosphate, or other cell types without changing the IC, which simplifies BOM management across product lines. The I2C interface keeps wiring to two lines (SDA/SCL), saving board space and GPIO on the host controller. The -40°C to 85°C range covers most industrial enclosures and outdoor telecom cabinets; if your application lives under the hood or in a freezer, you'll need a wider-temperature part. ## Package and rework considerations The 14-TSSOP package has a 4.40 mm body width. The Tube shipping medium means you get the parts in a rigid tube, not on a reel. ## Lifecycle and sourcing The BQ35100PW is listed as Active and ROHS3 compliant.","metaTitle":"BQ35100PW Battery Monitor, Multi-Chemistry, I2C, 14-TSSOP","metaDescription":"TI BQ35100PW battery monitor IC for multi-chemistry cells.
