1.5A Power Distribution Switch

TPS2553DBVT General Description

The TPS2553DBVT from Texas Instruments is a versatile power distribution switch that offers reliable protection for circuits in various low-voltage applications. With its wide voltage input range of 1.5V to 5.5V, this compact device is an excellent choice for portable electronics, battery-powered devices, and other space-constrained designs. The TPS2553DBVT features a low ON-resistance of typically 60mΩ, ensuring minimal power loss and high efficiency. Its current-limiting and thermal shutdown capabilities provide essential safeguards against overcurrent and overheating, protecting both the load and the switch itself from damage. Additionally, the device incorporates a soft-start feature to manage inrush currents during power-up, enhancing system reliability. Packaged in a small SOT-23 form factor, the TPS2553DBVT is a convenient solution for power management in compact designs
