TPS2065DBVT

Power Distribution Switches, Load Drivers Overview

The TPS2065DBVT is a single-channel, current-limited power-distribution switch designed for USB applications. It operates within an input voltage range of 4.5 V to 5.5 V and supports a continuous load current of 1 A. The device features a fixed current limit of 1.5 A with constant-current topology. Key electrical parameters include a maximum on-resistance of 96 mΩ, a typical turn-on time of 2.2 ms, and a typical fall time of 2.5 ms. It functions in an ambient temperature range of -40°C to +85°C and utilizes a SOT-23-5 surface-mount package.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DBVT' corresponds to the SOT-23-5 package configuration when sourcing. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain rated performance. Cross-reference the manufacturer's latest datasheet for any updates regarding moisture sensitivity levels or recommended soldering profiles prior to implementation.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel solution with integrated current limiting is required for 5V systems. It is suitable for designs needing compact footprint via the SOT-23-5 package. Consider alternatives like the TPS2065DGN if an MSOP package is preferred for thermal dissipation. Verify that the 1A continuous current rating aligns with the target load requirements and that the 1.5A trip point provides adequate margin against transient surges without nuisance tripping.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS20xxC series of power-distribution switches from Texas Instruments. The series includes variants with one, two, or three channels, such as the TPS2061, TPS2062, and TPS2063. These devices share similar protection features but differ in channel count and package options. The TPS2065 specifically denotes the single-channel variant optimized for standard USB power applications.

Power Distribution Switches, Load Drivers FAQ

What is the function of the EN pin?

The EN (Enable) pin controls the state of the internal switch. Driving this pin high turns the switch on, allowing current to flow to the load, while driving it low turns the switch off.

How does the device handle short-circuit conditions?

In the event of a short circuit, the device limits the output current to approximately 1.5 A using a constant-current topology. If the condition persists and causes excessive heating, thermal shutdown will activate to protect the device.
