The TPS2552DBVT-1 from Texas Instruments is a power distribution switch designed for applications needing precise current limiting or handling heavy capacitive loads and short circuits. It offers an adjustable current limit ranging from 75 mA to 1.7 A with ±6% accuracy at 1.7 A. The device operates within a voltage range of 2.5 V to 6.5 V and features an 85 mΩ high-side MOSFET.
Key features include a fast overcurrent response of 2 µs, reverse input-output voltage protection, and built-in soft start. The TPS2552DBVT-1 also provides 15 kV ESD protection per IEC 61000-4-2 with external capacitance. It is suitable for USB power switch applications and is available in a SOT-23-6 package for surface mounting.
This load switch is designed for reliability, incorporating over-temperature and undervoltage lockout (UVLO) fault protection. Its constant-current and latch-off versions, along with backward compatibility with TPS2550 and TPS2551, make it a versatile choice for various power management designs.
