TPS27082L

The TPS27082L from Texas Instruments is a high-side load switch IC integrating a Power PFET and control circuitry in a SOT-23 package. It operates over a wide input voltage range of 1.2 V to 8 V and can handle up to 3 A of current. The device features low ON-resistance, with typical values ranging from 32 mΩ at VGS = -4.5 V down to 155 mΩ at VGS = -1.2 V.

Key features include configurable turn-ON and turn-OFF slew rates, with a default minimum output rise time of 10 µs at 5 V input. It offers excellent OFF isolation even under fast input transients and a robust ON/OFF logic interface with hysteresis, supporting logic levels down to 1 V. The TPS27082L also provides protection against ESD, with HBM rated at 2000 V and CDM at 500 V.

This load switch is suitable for applications such as high-side load switches, inrush-current controls, power sequencing, and stand-by power isolation in portable devices. It is available in a compact SOT-23-6 package, measuring 2.9 mm x 1.6 mm x 0.75 mm, making it ideal for space-constrained designs. The device also boasts very low ON-state quiescent current (down to 1.2 µA) and very low OFF-state leakage current (typical 100 nA) for optimized system power efficiency.
