TPS2345PW

Hot Swap Controllers Overview

The TPS2345PW is a dual-output low dropout (LDO) voltage regulator manufactured by Texas Instruments. It features two independent linear regulators housed in a single 20-pin HTSSOP package. The device provides a 250 mA output channel and a 500 mA output channel, designed for applications requiring multiple regulated voltages from a single input source. It operates within an input voltage range of 3.641 V to 6 V, with a maximum absolute input voltage of 7 V. The regulator maintains a typical dropout voltage of 0.17 V and a maximum of 0.275 V. It includes integrated short-circuit protection and thermal shutdown capabilities. The component supports operation across an extended temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

Hot Swap Controllers Feature Summary

• Dual-output architecture providing independent 250 mA and 500 mA regulation channels
• Integrated SVS (Short-circuit and Voltage protection) for enhanced system safety
• Low dropout performance minimizing power loss during high load conditions
• Extended operating temperature range suitable for industrial applications

Hot Swap Controllers Applications

• Portable electronic devices requiring multiple voltage rails
• Industrial control systems needing reliable dual-supply regulation

• Battery-powered equipment utilizing efficient linear regulation

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm RoHS compliance status and lead times through authorized distributors. Ensure the procurement channel is authorized to guarantee genuine components. Check for any recent design changes or obsolescence notices from Texas Instruments before placing orders.

Hot Swap Controllers Selection Notes

Select this component when dual isolated outputs are necessary within a compact footprint. Consider the 250 mA/500 mA current distribution against total power dissipation limits. Evaluate input voltage stability relative to the specified 3.641 V minimum. Assess thermal management requirements given the HTSSOP-20 package constraints at full load.

Hot Swap Controllers Part Context

This part belongs to Texas Instruments' family of dual-output LDO regulators. It complements single-output variants by offering integrated dual-rail solutions. The HTSSOP-20 package allows for space-constrained designs compared to larger DIP options. It serves as a power management solution for systems transitioning from discrete regulator setups to integrated ICs.

Hot Swap Controllers Replacement Considerations

Direct substitutes include other TI dual-output LDOs with similar current ratings and pinouts. Verify compatibility with existing PCB layouts when replacing with equivalent parts from other manufacturers. Ensure thermal characteristics and dropout voltages meet original design specifications.
