TPS2065CDGN

Power Distribution Switches, Load Drivers Overview

The TPS2065CDGN is a single-channel, current-limited power-distribution switch designed for USB applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a continuous output current of 1 A with a fixed current limit of 2.9 A. The device features a maximum on-resistance of 130 mΩ, ensuring efficient power delivery. It includes built-in protections against overcurrent, overtemperature, and under-voltage lockout. The component is housed in an 8-MSOP PowerPAD package and functions reliably across an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates a single N-channel power switch with active high enable control for simplified interface.
• Provides constant-current topology for precise load protection during fault conditions.
• Includes thermal shutdown and under-voltage lockout mechanisms to safeguard the circuit.
• Features an integrated output discharge resistor to rapidly remove charge from downstream capacitors.

Power Distribution Switches, Load Drivers Applications

• USB hub power distribution circuits
• Peripheral device power switching
• Portable equipment power management

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'CDGN' corresponds to the MSOP-PowerPad package and commercial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as indicated in official documentation. Ensure the ordering part number matches the required tape-and-reel or tube packaging format specified by the manufacturer for the CDGN variant.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single channel with 1 A continuous current capability is required for 5 V systems. It is suitable for designs needing fast turn-on/turn-off times and integrated fault protection. Consider alternative pin counts or channel numbers if multiple outputs are needed. Verify that the 130 mΩ on-resistance meets the system's voltage drop requirements.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS206x family of current-limited power switches. It shares functional similarities with other members like the TPS2061 (single channel) and TPS2066 (dual channel), but differs in channel count and specific package options. The TPS2065CDGN specifically denotes the single-channel variant in the MSOP-PowerPAD package.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2065DGNR offers the same electrical specifications in a tape-and-reel package. TPS2061 provides identical single-channel performance in different packages. Cross-reference datasheets for exact pinout and thermal characteristics before substitution.
