Product details

Multi-chemistry battery monitor for 1-4 series cells

The Texas Instruments BQ34110PW is a multi-chemistry battery monitor that tracks charge and health for 1 to 4 series cells. It communicates over an I²C bus, making it straightforward to integrate with a host MCU in a portable or standby-power system. The 14-TSSOP package keeps the footprint small for space-constrained battery packs.

Industrial temperature range and package fit

Rated for -40°C to 85°C ambient, this monitor suits outdoor telecom cabinets, industrial UPS battery trays, and electric-vehicle auxiliary packs that see temperature swings. The 14-TSSOP body (4.40 mm width) is a common footprint; verify land pattern against your existing 14-pin TSSOP layout.

Sourcing and lifecycle

The BQ34110PW carries an Active product status with ROHS3 compliance.

Frequently asked questions

What is the interface of BQ34110PW?

The BQ34110PW uses an I²C interface for communicating cell voltage, current, and temperature data to the host controller.

How many cells does BQ34110PW support?

It monitors 1 to 4 series cells, covering a range from single-cell portable packs up to 4S battery stacks.

What is BQ34110PW's closest functional second-source?

The BQ2084DBT-V143 is a functional peer — also a surface-mount battery monitor, but limited to Lithium Ion/Polymer chemistry and a -20°C to 85°C range, with an SMBus interface instead of I²C. Verify pin compatibility and firmware porting before substituting.
