TPS2110PW

Overview

The TPS2110PW is an autoswitching power multiplexer manufactured by Texas Instruments, designed for seamless source selection in portable electronics. It features a 2:1 input-to-output ratio with internal N-channel switches, supporting a supply voltage range of 2.8V to 5.5V and delivering a maximum output current of 750mA. The device operates within a temperature range of -40°C to 85°C and utilizes an 8-TSSOP surface-mount package. Key timing parameters include a turn-on delay of 500 µs and a turn-off delay of 3 ms, ensuring controlled switching behavior.

Feature Summary

• Autoswitching functionality enables automatic source selection between two inputs without external control logic
• Integrated N-channel MOSFET switches provide low on-resistance for efficient power transfer
• Compact 8-TSSOP package design supports space-constrained handheld and mobile device applications

Applications

• Handheld devices requiring redundant power sources
• Mobile equipment utilizing battery and adapter power management
• Portable electronics needing seamless power source transitions

Procurement Notes

Verify the specific suffix 'PW' corresponds to the 8-TSSOP package variant when sourcing. Confirm RoHS compliance status and manufacturing date codes against current distributor documentation. Ensure compatibility with system voltage requirements ranging from 2.8V to 5.5V. Cross-reference the manufacturer part number TPS2110PW with official Texas Instruments datasheets to validate pinout and electrical specifications prior to integration.

Selection Notes

Select this component for applications requiring automatic power source switching between two inputs. It is suitable for systems operating within the 2.8V to 5.5V range and demanding up to 750mA output current. Consider the 8-TSSOP package for surface-mount assembly constraints. Evaluate the 500 µs turn-on and 3 ms turn-off delays against system timing requirements to ensure proper power sequencing and load protection.
