For a 1.7 A continuous output, the actual limit falls between roughly 1.67 A and 1.73 A — tight enough to protect a 1.5 A nominal load with margin. The 4.5 V to 18 V input range covers common 5 V and 12 V rails, plus intermediate bus voltages up to 18 V.","metaTitle":"Texas Instruments TPS25921AD Electronic Fuse, 1.7A, 8-SOIC","metaDescription":"Texas Instruments TPS25921AD electronic fuse, 1.7A output, ±2% accuracy, 4.5V–18V input, -40°C to 125°C.
