Battery monitor for multi-chemistry packs
The Texas Instruments BQ35100PW is a battery monitor IC designed for multi-chemisty cells, communicating over an I2C interface. 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.
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 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.
