Frequently Asked Questions
What continuous current can TPS2231PWPR handle, and over what input voltage range does it operate?
TPS2231PWPR supports up to 1.3 A continuous load current over a 2.7 V to 6 V input voltage range, making it suitable for 3.3 V and 5 V PCIe card power rails that require controlled hot-plug switching without damaging sensitive downstream components.
How does TPS2231PWPR limit inrush current during PCIe card insertion?
TPS2231PWPR uses a programmable slew rate control on its gate drive to ramp the external P-channel FET gradually during hot insertion, limiting inrush current below the PCIe specification threshold of approximately 3 A peak, thereby protecting both the card and backplane connectors from stress.
When would an engineer choose TPS2231PWPR over a simpler load switch for a server backplane design?
Engineers choose TPS2231PWPR when the PCB must comply with PCI Express hot-plug sequencing requirements, because the device provides integrated fault detection, overcurrent limiting, and gate drive circuitry in a single HTSSOP-24 package, eliminating the need for multiple discrete components across a 2.7 V to 6 V rail.
