TPS2061DG4

Power Distribution Switches, Load Drivers Overview

The TPS2061DG4 is a single-channel, current-limited power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 5.5V and supports a continuous output current of 1A. The device features an N-channel MOSFET with a typical on-resistance of 70 milliohms. It is housed in a 8-SOIC package with a width of 3.90mm. Key protection mechanisms include fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). The component is designed for high-side switching applications and includes a status flag feature.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates a single high-side N-channel power switch with low on-resistance for efficient power distribution.
• Provides comprehensive fault protection including fixed current limiting, thermal shutdown, and under-voltage lockout.
• Includes a status flag output to indicate the operational state of the switch.

Power Distribution Switches, Load Drivers Applications

• USB power distribution circuits
• Peripheral port protection
• Battery-powered equipment power management

Power Distribution Switches, Load Drivers Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status matches project requirements. Check for obsolescence notices or lifecycle changes from Texas Instruments before finalizing designs. Ensure the 8-SOIC package footprint aligns with PCB layout specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring a single channel of protected power switching. Compare against TPS2062 or TPS2063 if multiple channels are needed. Consider the 70 milliohm on-resistance for power loss calculations. Verify that the 2.7V minimum operating voltage suits the system's power rail.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS206x family of USB power switches. It shares functional similarities with TPS2062 and TPS2065 but differs in channel count and specific electrical characteristics. The DG4 suffix indicates a lead-free, RoHS-compliant variant of the standard TPS2061D.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2061D is a direct equivalent non-RoHS version. For multi-channel needs, consider TPS2062 (dual) or TPS2063 (triple). Single-channel alternatives with different packages include TPS2065CDGN.
