TPS2105DBVT Description

Short technical summary and product information.

The TPS2105DBVT is a source selector switch from Texas Instruments designed to manage power source selection in systems requiring seamless switching between two inputs. It incorporates internal N and P-Channel FETs to provide a 2:1 multiplexing function with inrush current control and reverse current blocking.

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V, with maximum output currents of 0.5A on IN1 and 0.1A on IN2. The typical on-resistance is 250 mΩ for the IN1 channel and 1300 mΩ for IN2, while the quiescent current is extremely low at 0.75 µA. Additional protection features include thermal shutdown.

 

The device is housed in a SOT-23-5 package (also designated as SC-74A, SOT-753) and supports surface mount mounting. It operates over a temperature range of -40°C to 85°C.
