TPS22990DMLR

Power Distribution Switches, Load Drivers Overview

The TPS22990DMLR is a single-channel high-side load switch manufactured by Texas Instruments, designed for power distribution applications. It operates within an input voltage range of 600 mV to 5.5 V and supports a continuous output current of 10 A. The device features a typical on-resistance of 3.9 mΩ and a maximum on-resistance of 4.8 mΩ. Key timing parameters include a maximum turn-on time of 34 µs and a maximum turn-off time of 5.4 µs. It is housed in a compact 10-WSON (3x2 mm) package with exposed pad, suitable for surface mount installation. The component functions reliably across an extended temperature range from -40°C to +105°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix DMLR corresponds to the 10-WSON package and tape-and-reel quantity of 3000 units. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for your assembly process. Ensure the ordering information matches the exact electrical specifications required for your design implementation.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single channel capable of handling 10 A at up to 5.5 V is required. The low on-resistance minimizes power dissipation compared to higher resistance alternatives. Consider the 10-WSON footprint constraints and thermal performance needs. Verify that the non-inverting control logic aligns with your system's GPIO or control architecture.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS22990 series of load switches from Texas Instruments. It is functionally similar to the TPS22990DMLT, which shares identical electrical characteristics but differs in packaging format. The series is designed for portable electronics and general-purpose power distribution where space efficiency and high current capability are critical.

Power Distribution Switches, Load Drivers Replacement Considerations
