TPS2034DG4

Power Distribution Switches, Load Drivers Overview

The TPS2034DG4 is a single-channel, high-side power switch manufactured by Texas Instruments. It features an N-channel MOSFET output capable of delivering up to 2A continuous load current. The device operates within a supply voltage range of 2.7V to 5.5V and utilizes a non-inverting logic interface for control. Integrated protection mechanisms include fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). The component is housed in an 8-SOIC surface-mount package with a maximum on-resistance of 33 milliohms.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free compliance when sourcing. Confirm the manufacturer designation matches Texas Instruments specifications. Ensure the 8-SOIC package dimensions align with PCB layout requirements. Cross-reference the datasheet revision date to validate parameter accuracy against current production standards.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for designs requiring a single high-side switch with integrated fault protection. It is suitable for low-voltage systems operating between 2.7V and 5.5V. Consider the 33 milliohm on-resistance for efficiency calculations. Evaluate the need for a status flag output before choosing over variants without diagnostic capabilities.

Power Distribution Switches, Load Drivers Part Context

The TPS2034 belongs to the TPS203x family of protected power switches from Texas Instruments. This series provides high-side switching solutions with built-in safeguards against overcurrent and overheating. The DG4 variant specifically denotes a lead-free version of the standard TPS2034DR part, maintaining identical electrical performance while adhering to environmental compliance standards.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2034DR serves as the primary equivalent part number. Verify pin compatibility and package dimensions before substitution. Ensure replacement parts meet the same 2A current rating and voltage specifications.
