Product details

Over-voltage watchdog for 2-3 cell Li-ion packs

The Texas Instruments BQ294592DRVT is a dedicated battery protection IC designed to guard 2-3 series lithium-ion cells against over-voltage faults. It monitors each cell in the stack and triggers an external discharge FET when any cell exceeds the over-voltage threshold, preventing the pack from charging into an unsafe state.

Cell count and protection scope

This device handles 2 to 3 cells in series — a common range for 7.2 V to 11.1 V nominal Li-ion packs. The fault protection is limited to over-voltage only; there is no on-chip over-current or short-circuit detection, so the system designer must add those functions externally if the application requires them. The single-function focus keeps the die small and the BOM cost low for designs where over-voltage is the primary safety concern.

Package and footprint for tight packs

Active lifecycle — no near-term obsolescence concern

The 6-WSON package is a current, widely used footprint, so supply continuity looks stable for the foreseeable future.

Frequently asked questions

Is BQ294592DRVT compatible with 3-cell Li-ion?

Yes. The BQ294592DRVT is specified for 2 to 3 cells in series, covering 3-cell Li-ion packs with a nominal voltage of 11.1 V. It monitors each cell for over-voltage faults and triggers protection when any cell exceeds the threshold.

What is the replacement for BQ294592DRVT?

There is no official TI replacement listed for the BQ294592DRVT. The part remains Active in production, so a replacement is not needed for current designs. For a functional alternative, the BQ79612PAPRQ1 is a different class — automotive-grade 1-cell monitor with SPI/UART interface and over-temperature protection — not a pin-compatible drop-in.

Can BQ294592DRVT be used with 4-cell Li-Ion?

No. The BQ294592DRVT is designed for 2 to 3 cells only. A 4-cell pack exceeds the device's specified cell-count range and would leave the fourth cell unprotected. For 4-cell applications, look at a different battery-protection IC rated for 4 or more series cells.
