It integrates overcurrent, overtemperature, overvoltage, undervoltage, and short-circuit fault protection into a single 20-TSSOP package. The device operates over -40°C to 85°C, suiting it for industrial battery packs, power tools, and outdoor energy storage systems where the pack sees ambient temperature swings. ## What the ratings mean for your BOM The 3 to 5 cell range is the primary fit parameter. The overcurrent and short-circuit detection thresholds are set by external sense resistors. ## Lifecycle and sourcing reality For a production BOM, this part is a stable line item through standard distribution. ## Package and handling The TSSOP body is moisture-sensitive. Surface-mount assembly; no through-hole variant exists for this function.","metaTitle":"BQ7790512PW Battery Protection IC, 3-5 Cell Li-Ion, 20-TSSOP","metaDescription":"TI BQ7790512PW Li-Ion battery protection IC for 3-5 cells.
