TPS2051DR

Power Distribution Switches, Load Drivers Overview

The TPS2051DR is a single-channel, high-side power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an output current limit of 900 mA. The device features fault reporting capabilities and an active-high enable input. It is housed in an 8-pin SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range from -40 °C to +85 °C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates a high-side MOSFET with fixed current limiting for load protection
• Provides fault status reporting via the FLTR pin during overcurrent or thermal events
• Features controlled rise and fall times to minimize inrush current during switching

Power Distribution Switches, Load Drivers Applications

• USB port power distribution and hub circuits
• Peripheral device power management in computing systems
• General-purpose high-side load switching applications

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DR' corresponds to the 8-SOIC package and tape-and-reel packaging configuration. Confirm that the required fault reporting functionality aligns with system design requirements, as this variant includes the FLTR pin. Ensure compatibility with the specified 2.7 V to 5.5 V supply voltage range for the target application environment.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel solution with integrated fault reporting is required. The 900 mA current limit suits moderate-load USB peripherals. Consider the SOIC-8 package for standard PCB layouts. Evaluate if the active-high enable logic matches the control interface. Compare against variants like TPS2051BDR if different current limits or packages are needed.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS20xx family of current-limited power switches designed for USB and general power distribution. Unlike the dual-channel TPS2052 or triple-channel TPS2057, the TPS2051 offers a single channel. It differs from the TPS2051C series which targets 5V-only applications with lower on-resistance. The DR suffix denotes the SOIC-8 surface-mount package.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes include TPS2051BD (same function, different package) or TPS2051BDR (same function, same package). Cross-family alternatives like TPS2052DR offer dual channels but require layout adjustments.
