TPS2114PWG4

Overview

The TPS2114PWG4 is an OR controller and source selector switch manufactured by Texas Instruments. It features a single channel with N-channel internal switches, designed for power distribution applications. The device operates within a supply voltage range of 2.8V to 5.5V and supports a maximum output current of 750mA. It utilizes an 8-TSSOP package with a width of 4.40mm. The component functions as a 2:1 input-to-output ratio switcher, incorporating specific timing characteristics including a turn-on delay of 500µs and a turn-off delay of 3ms. It is rated for operation between -40°C and +85°C.

Feature Summary

• Functions as an OR controller and source selector switch for managing multiple power inputs.
• Integrates N-channel internal switches to facilitate efficient power path control.
• Provides automatic selection between two input sources to ensure continuous power delivery.

Applications

• Handheld devices
• Mobile equipment power management
• Systems requiring redundant power source selection

Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to confirm package type and RoHS compliance status. Ensure that the procurement channel provides valid traceability for electronic components. Cross-reference the manufacturer part number with the distributor catalog to avoid substitution errors. Confirm availability status as inventory levels may fluctuate. Validate that the received units match the specified 8-TSSOP package dimensions.

Selection Notes

Select this component when designing circuits requiring automatic source selection between two power rails. Consider the 750mA output current limit and the 2.8V to 5.5V operating voltage range for compatibility. Evaluate the 500µs turn-on and 3ms turn-off delays against system timing requirements. Ensure the 8-TSSOP package fits the available PCB footprint. Compare performance metrics with alternative OR controllers if higher current or different voltage ranges are needed.

Part Context

The TPS2114 belongs to the Texas Instruments family of OR controllers and ideal diode solutions. These components are engineered to manage power flow in systems with multiple input sources. The PWG4 suffix indicates a specific tape and reel packaging variant compliant with RoHS standards. This series supports applications where seamless switching between power sources is critical for system reliability.

Replacement Considerations

Public confirmed substitute part numbers include TPS2114PW. Verify pinout compatibility and electrical specifications before replacement. Check for any differences in packaging or marking codes. Consult official datasheets for both parts to ensure functional equivalence in the target application.
