Housed in a SOT-23-8 package (supplier device package TSOT-23-8), it mounts on the board with a standard surface-mount footprint. ## Single-cell protection with three fault triggers The IC monitors a single battery cell (1-cell configuration) and asserts protection on three fault conditions: over-current, over-temperature, and short-circuit. The over-current threshold is set by an external sense resistor; the thermal shutdown triggers when the die temperature exceeds the internal limit, protecting the pass FET and the load. Reverse battery protection is the primary function — the IC blocks negative voltage at the input before it reaches the load, eliminating the need for a series Schottky diode and its forward voltage drop. This preserves headroom for the downstream regulator, especially at low input voltages during cranking. ## Active lifecycle and compliance for production BOMs Sourced through authorized distribution channels, the part is quoted to order against a BOM quantity.","metaTitle":"Texas Instruments LM74501QDDFRQ1 Battery Protection IC","metaDescription":"Texas Instruments LM74501QDDFRQ1 automotive battery protection IC, 3.2V-65V reverse protection, SOT-23-8, active production, ROHS3.
