What are the key features of TPS22949AYZPR?
- Integrated current limiting with adjustable threshold protects downstream circuits from inrush and fault currents in 1.62 V to 4.5 V systems
- Low-noise output regulation capability allows the load switch to act as an LDO-like filter for noise-sensitive analog and RF loads
- Ultra-compact 8-ball DSBGA (R-XBGA-B8) package enables minimal board area usage in space-constrained IoT and wearable designs
What is TPS22949AYZPR used for?
The TPS22949AYZPR is suited for power sequencing and protection in IoT sensors, wearables, and handheld devices operating from 1.62 V to 4.5 V single-cell Li-Ion or regulated rails. Its low-noise regulation makes it valuable for powering sensitive RF front-ends and precision ADCs where supply noise directly impacts signal quality. The current-limit feature also provides built-in protection for USB accessories and hot-plug interfaces.

Frequently Asked Questions
What input voltage range does the TPS22949AYZPR support and what battery chemistries does that cover?
The TPS22949AYZPR supports an input voltage range of 1.62 V to 4.5 V, covering single-cell Li-Ion/Li-Polymer batteries (2.5 V to 4.2 V), alkaline AA cells, and regulated 1.8 V or 3.3 V power rails. This broad range makes it versatile for portable IoT, wearable, and sensor node designs without additional voltage translation.
How does the low-noise regulation in the TPS22949AYZPR benefit sensitive analog circuits?
The TPS22949AYZPR includes an integrated low-noise regulation stage that attenuates power supply ripple and high-frequency noise on the output rail. For precision ADCs or RF receivers powered from shared switching regulator rails, this noise suppression can reduce spurious noise by several millivolts, improving SNR and dynamic range in 1-channel load applications.
What package does the TPS22949AYZPR use and how small is the PCB footprint for high-density designs?
The TPS22949AYZPR uses an 8-ball DSBGA (R-XBGA-B8) package with a ball pitch of 0.4 mm, making it one of the smallest load switch packages available and ideal for wearables and compact IoT modules where board space is at a premium. The 1.62 V minimum operating voltage aligns well with near-depleted battery operation in 1-channel load-switched rails.
