Product details

What this part is and where it fits

The Texas Instruments BQ34Z110PWR is a battery monitor IC from the Impedance Track™ series, purpose-built for lead-acid chemistries. It reports state-of-charge, voltage, and temperature over an HDQ or I²C bus to a host controller. The -40°C to 85°C operating range and surface-mount 14-TSSOP package make it a natural fit for industrial backup-power systems, UPS battery packs, telecom rectifiers, and outdoor solar-storage monitors where the battery chemistry is fixed to lead-acid.

Lifecycle and supply posture

The BQ34Z110PWR is listed as Active with ROHS3 compliance.

Frequently asked questions

What interface does BQ34Z110PWR support?

It supports both HDQ and I²C interfaces for communication with a host microcontroller.

Is BQ34Z110PWR compatible with lithium batteries?

No. This part is designed for lead-acid chemistry only. For lithium-ion or lithium-polymer applications, consider a different gauge IC such as the BQ79612PAPRQ1 or BQ2084DBT-V143.

What is the equivalent of BQ34Z110PWR?

There is no direct pin-compatible second source for this lead-acid gauge. The peers BQ79612PAPRQ1 and BQ2084DBT-V143 serve different chemistries and interfaces — they are functional alternatives only if your system can switch to Li-ion and a different bus protocol.
