Power Distribution Switches, Load Drivers datasheet and documents for TPS2051BDG4

TPS2051BDG4

Power Distribution Switches, Load Drivers Overview

The TPS2051BDG4 is a single-channel, current-limited 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 capacity of 500 mA with a fixed current limit of 900 mA. The device features a low on-resistance of 135 mΩ maximum. It incorporates fault protection mechanisms including thermal shutdown and under-voltage lockout (UVLO). The component is housed in an SOIC-8 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

Integrates high-side MOSFET with current limiting for protected power distribution
Includes built-in thermal shutdown and under-voltage lockout for fault management
Features act-high enable logic for straightforward control interface

Power Distribution Switches, Load Drivers Applications

USB port power switching and protection
Peripheral circuit power distribution
Battery-powered system load switching

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliance as per manufacturer standards. Confirm that the SOIC-8 tube packaging matches the required handling specifications. Ensure the part number corresponds to the discontinued status noted in distributor records before finalizing procurement plans.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel high-side switch with integrated fault protection is required. It is suitable for applications needing current limiting below 1 A and operation at standard USB voltages. Consider the SOIC-8 package size and thermal characteristics for PCB layout constraints.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2051B family of power distribution switches designed for protecting downstream circuits. It serves as a robust solution for managing power delivery in portable electronics and peripheral interfaces where overcurrent and thermal faults must be managed autonomously.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2051BDG4 is listed as obsolete. Potential substitutes include TPS2051BD or TPS2051BDBV, though pinout and package differences require verification.
