What are the key features of TPS2097DG4?
- Quad independent high-side MOSFET switches with 0.25 A per channel continuous and 0.5 A peak current limit for 4 simultaneous power rails from a single IC
- Integrated overcurrent, thermal shutdown, and undervoltage lockout protection on each channel with active-low fault reporting for system fault management
- 2.7 V to 5.5 V input supply range with CMOS/TTL-compatible enable inputs for direct interface to 3.3 V or 5 V microcontrollers in USB hub and multiport power designs
What is TPS2097DG4 used for?
The TPS2097DG4 is designed for USB hub power distribution, multi-port charger designs, and embedded systems where four independent switchable 5 V or 3.3 V power outputs are required under microcontroller supervision. Its integrated protection on each channel prevents a single faulted load from collapsing the shared power bus, making it suitable for industrial I/O card power sequencing and portable device accessory port management. The quad channel architecture reduces BOM count compared to using four discrete power switches.

Frequently Asked Questions
What is the continuous and peak current rating per channel on the TPS2097DG4?
Each of the 4 high-side MOSFET channels in the TPS2097DG4 supports 0.25 A continuous output current with a 0.5 A peak current limit before the overcurrent protection activates. This is sized for USB bus-powered accessories at 100 mA to 200 mA per port, with the 0.5 A limit providing headroom for inrush current during capacitive load startup without nuisance tripping.
How does the TPS2097DG4's overcurrent protection help protect a USB hub design from a shorted peripheral?
When a channel's current exceeds the 0.5 A peak threshold, the TPS2097DG4 latches off that channel and asserts its active-low fault pin, which a host microcontroller can read to identify which port faulted. The remaining 3 channels continue operating normally, so a shorted USB peripheral on one port does not interrupt power delivery to the other 3 ports sharing the same IC.
What supply voltage range does TPS2097DG4 support, and is it compatible with both 3.3 V and 5 V USB power buses?
The TPS2097DG4 operates from a 2.7 V to 5.5 V input supply, covering both the 3.3 V and 5 V rails used in USB and embedded systems. The enable inputs are CMOS/TTL compatible, accepting logic high thresholds from a 3.3 V microcontroller GPIO without requiring level shifters, simplifying system integration.
How does integrating 4 switches in a single TPS2097DG4 compare to using discrete MOSFETs for a 4-port power distribution design?
A single TPS2097DG4 in a 16-pin SOIC replaces 4 discrete P-channel MOSFETs plus their gate resistors, pull-ups, and separate current-sense circuits. The integrated thermal and overcurrent protection also eliminates 4 separate current-limit comparators, reducing BOM count by approximately 20 to 30 components and shrinking PCB area by 50% or more compared to a fully discrete equivalent design.
