What are the key features of TPS2104DBVT?
- Dual-input single-output architecture enables automatic priority-based power source selection between 2 supply rails
- Integrated MOSFET switch in 5-pin SOT-23 minimizes PCB footprint for portable and space-constrained power management
- Built-in control logic replaces discrete OR-ing diodes and MOSFETs, reducing BOM count and reverse-current protection complexity
What is TPS2104DBVT used for?
The TPS2104DBVT is ideal for portable devices requiring seamless switchover between two power sources such as USB bus power and a battery backup rail. Its integrated dual-input priority logic ensures the higher-priority source drives the output load without glitches during source transitions. The compact SOT-23 footprint suits wearables, IoT nodes, and handheld instruments where board space is at a premium.

Frequently Asked Questions
How does TPS2104DBVT manage power source priority between 2 input rails without external logic?
TPS2104DBVT uses internal priority-select control logic to automatically connect the higher-priority input to the output while blocking the lower-priority source. This allows seamless handoff between, for example, a 5 V USB rail (priority 1) and a 3.7 V Li-ion battery (priority 2) with no firmware intervention, protecting the load from momentary voltage drops during switchover.
What package does TPS2104DBVT use and how does it fit into compact wearable device PCB layouts?
TPS2104DBVT is packaged in a 5-pin SOT-23 measuring approximately 1.6 mm × 2.9 mm, one of the smallest standard packages available for integrated power switches. This footprint consumes less than 5 mm² of board area, enabling integration into wearable fitness trackers, wireless earbuds, and miniature IoT sensor nodes where every square millimeter matters.
What reverse-current protection benefit does TPS2104DBVT provide compared to passive OR-ing diodes?
Unlike passive Schottky OR-ing diodes with 300 mV to 500 mV forward voltage drop, TPS2104DBVT uses low-RDS(on) MOSFETs with active reverse-current blocking. This eliminates conduction losses at the power switch, improving battery run-time efficiency in 2-source systems and avoiding the thermal dissipation associated with diode drops at load currents above 100 mA.
In a USB-powered handheld meter with a coin-cell backup, how does TPS2104DBVT simplify the power architecture?
TPS2104DBVT consolidates the 2-input OR-ing function into a single 5-pin SOT-23 device, replacing a discrete solution of 2 P-channel MOSFETs, gate resistors, and Schottky diodes. It maintains output voltage continuity during USB removal by switching to the coin-cell rail within microseconds, protecting ADC reference circuits from supply transients during power-source transitions.
