TPS2393PWG4

Hot Swap Controllers Overview

The TPS2393PWG4 is a single-channel hot-swap voltage controller manufactured by Texas Instruments. It operates within an input supply range of -20 V to -80 V, designed for negative voltage systems such as -48 V telecommunications infrastructure. The device integrates protection features including overvoltage lockout and current limiting. It functions in the industrial temperature range from -40 °C to +85 °C. The component is housed in a 14-pin TSSOP surface-mount package with dimensions of 5 mm length, 4.4 mm width, and 1.15 mm height. Quiescent current is specified at 1.7 mA.

Hot Swap Controllers Feature Summary

• Integrates full-featured hot-swap control for safe insertion and removal of circuit boards under load
• Provides comprehensive protection against overvoltage, undervoltage, and short-circuit conditions
• Supports configurable threshold settings for precise system monitoring and fault management

Hot Swap Controllers Applications

• -48 V telecommunications power distribution systems
• Industrial equipment requiring safe board insertion
• Negative voltage backplane power architectures

Hot Swap Controllers Procurement Notes

Verify the suffix G4 indicates lead-free compliance and RoHS standards when sourcing. Confirm the PW variant corresponds to the TSSOP-14 package rather than the DBT TSSOP-44 version. Ensure the specific ordering code matches the required thermal and pin configuration for the target PCB layout. Cross-reference manufacturer documentation for any recent product change notices affecting material composition or assembly processes.

Hot Swap Controllers Selection Notes

Select this component for applications requiring robust protection in negative voltage environments up to -80 V. The single-channel design suits individual rail management. Consider the TSSOP-14 footprint constraints during layout. Verify that the -40 °C to +85 °C operating range meets environmental requirements. Compare quiescent current specifications against system power budget constraints.

Hot Swap Controllers Part Context

This part belongs to the TPS2393A series of hot-swap controllers from Texas Instruments. It serves as a specialized power management integrated circuit within the broader PMIC category. The device complements other TI solutions like the TPS2410 and TPS2330 by offering dedicated protection for high-voltage negative rails. It is distinct from PoE switches like the TPS23861.

Hot Swap Controllers Replacement Considerations

The TPS2393APWR is a reel-packaged equivalent within the same family. The TPS2393DBT offers a 44-pin TSSOP variant with different physical dimensions.
