TPS25210ARPWR

The Texas Instruments TPS25210ARPWR is an active electronic fuse (eFuse) with integrated reverse polarity protection. It is designed for power management applications, offering a wide operating input voltage range from 2.7 V to 5.7 V, with an absolute maximum continuous voltage of 28 V. This device features integrated back-to-back FETs with a low typical on-resistance of 31 mΩ.

The TPS25210ARPWR provides a current limit with a maximum rating of 4.44 A and a minimum of 0.5 A. It includes features such as adjustable soft start, an analog current monitor, a fault output, overvoltage clamping with pin-selectable thresholds (3.8 V, 5.7 V), a power good signal, and always-on reverse current blocking. The device also incorporates thermal shutdown and adjustable undervoltage lockout (UVLO).

Packaged in a 10-VQFN-HR (2x2) surface-mount package, this eFuse is suitable for applications requiring robust power protection. Its ideal diode operation ensures true reverse current blocking, protecting sensitive circuitry from reverse voltage conditions. The fast overvoltage clamp responds in typically 5 µs.

Key electrical characteristics include a typical quiescent current of 0.411 mA and a maximum of 0.593 mA. The operating temperature range is from -40°C to 125°C. This component is recognized under UL standards IEC62368 and UL2367.
