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.","metaTitle":"BQ294592DRVT Battery Protection IC, 2-3 Cell Li-Ion, 6-WSON","metaDescription":"TI BQ294592DRVT battery protection IC for 2-3 cell Li-ion packs.

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."},{"question":"What is the replacement for BQ294592DRVT?","answer":"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."},{"question":"Can BQ294592DRVT be used with 4-cell Li-Ion?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ294592DRVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ294592DRVT when reusing this data.
