What are the key features of TPS2114APWG4?
- Automatic power-source selection between 2 input rails as low as 1.5 V with adjustable switching threshold
- Low quiescent current and minimal voltage drop enabling efficient power path management in battery-backed designs
- 8-pin TSSOP package with 0.25 mm lead pitch for compact dual-supply switchover on space-constrained PCBs
- Supports a minimum 2.8 V at one power pin to enable low-voltage switching down to 1.5 V on the secondary rail
What is TPS2114APWG4 used for?
The TPS2114APWG4 is designed for portable electronics, wearables, and embedded systems requiring seamless switchover between a primary battery and a backup power supply without interruption to the load. Its adjustable threshold and 1.5 V minimum operating voltage make it suitable for 3.3 V and lower-voltage microcontroller rails in IoT sensor nodes and handheld instruments. The compact 8-pin TSSOP footprint keeps board area to a minimum in USB-powered or Li-ion battery-backed applications.

Frequently Asked Questions
What is the minimum input voltage the TPS2114APWG4 can switch between its two supply rails?
TPS2114APWG4 can switch a voltage as low as 1.5 V on one channel provided the other input power pin supplies at least 2.8 V. This 1.5 V minimum enables it to manage 1.8 V and 3.3 V dual-supply rails commonly found in low-power MCU and sensor systems, covering a wide range of portable designs.
How many channels does TPS2114APWG4 support, and what package does it come in for compact board layouts?
TPS2114APWG4 is a 2-channel power-source selector packaged in an 8-pin TSSOP with 0.25 mm lead pitch, occupying less than 10 mm² of board area. The small footprint makes it practical for tight PCB layouts in wearables and portable instruments where board real estate is critical.
Can the switching threshold of TPS2114APWG4 be adjusted, and why does that matter for battery-powered designs?
Yes, TPS2114APWG4 offers an adjustable threshold allowing designers to set the crossover point to match the specific battery chemistry discharge curve, such as switching at 3.0 V for Li-ion or 2.8 V for alkaline cells. Precise threshold control prevents premature switchover and maximizes usable battery capacity, extending runtime by tens of minutes in typical IoT sensor nodes.
When should a designer choose TPS2114APWG4 over a simple diode OR-ing circuit for power rail redundancy?
Unlike diode OR-ing, which drops 0.3 V to 0.7 V per diode and dissipates power proportional to load current, TPS2114APWG4 uses a MOSFET-based switch with milliohm on-resistance, keeping voltage drop below 50 mV at typical load currents of 100 mA to 2 A. This makes it the preferred choice when load regulation must stay within 1% and thermal budget is limited in compact enclosures.
