Applications
The TPS22990DMLT is designed for power distribution and hot-swap applications in servers, industrial controllers, and telecom line cards where high-current rails must be switched safely without triggering over-current faults. Its resistor-programmable slew rate enables system designers to limit inrush current spikes when energizing large bulk capacitors on 5 V or 3.3 V bus rails. The device is also used in battery-powered portable electronics for load isolation, power gating of high-current peripherals, and sequenced power-on/power-off control of subsystem modules.

Frequently Asked Questions
What is the maximum current rating of the TPS22990DMLT?
The TPS22990DMLT supports up to 10 A continuous load current, making it one of the higher-current load switches in its class. This rating enables it to power high-current subsystems such as disk drives, GPU memory, FPGAs, and high-power RF modules directly without an external power FET.
What input voltage range does the TPS22990DMLT support?
The TPS22990DMLT operates with an input voltage from 0.6 V to 5.5 V, covering common power rails including 0.8 V FPGA core, 1.8 V, 2.5 V, 3.3 V, and 5 V USB or adapter supplies. This wide range makes it versatile for multi-rail power distribution in complex system boards.
How is inrush current controlled in the TPS22990DMLT?
The TPS22990DMLT uses a single external resistor connected to the RSET pin to program the output voltage slew rate during turn-on. A higher resistance slows the slew rate, reducing peak inrush current into downstream bulk capacitors. This resistor-based control eliminates the need for complex soft-start capacitor networks.
What package does the TPS22990DMLT use?
The TPS22990DMLT is housed in a 10-pin DML (WSON-style) package with JEDEC code R-PDSO-N10. The leadless no-lead package provides excellent thermal performance through its exposed pad, which helps dissipate the heat generated at 10 A load currents, and supports fine-pitch PCB assembly.
What are the typical applications for the TPS22990DMLT?
Typical applications include server power distribution units, telecom blade hot-swap circuits, industrial PLC power sequencing, and high-current peripheral power gating in desktop and embedded computing platforms. The device is also used in USB power delivery circuits, solid-state drive power isolation, and battery pack protection switches for portable consumer electronics.
