TPS2493PWR

Overview

The TPS2493PWR is a positive high-voltage power-limited hot swap controller manufactured by Texas Instruments. It operates within a supply voltage range of 9 V to 80 V and features a single channel. The device utilizes a 14-TSSOP surface-mount package and draws a typical operating supply current of 1 mA. It supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Programmable power foldback protection ensures external FETs remain within safe operating area during overloads.
• Integrated surge current limiting and controlled load turn-on capabilities for safe system initialization.
• Configurable current limit and fault timer settings protect both the power source and downstream loads.

Applications

• Telecommunications equipment requiring safe board insertion
• Industrial control systems with high-voltage bus architectures
• Data center infrastructure managing hot-pluggable server blades

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS3 compliance requirements for your target market. Cross-reference the datasheet revision history to confirm compatibility with existing design files and manufacturing processes before finalizing procurement orders.

Selection Notes

Select this controller when designing systems requiring precise power management for external N-channel MOSFETs in high-voltage environments. The programmable nature allows customization of protection thresholds to match specific load characteristics. Consider the thermal performance of the TSSOP-14 package relative to the expected ambient temperatures and heat dissipation constraints of the final application enclosure.

Part Context

This component belongs to the TPS249x series of hot swap controllers, designed specifically for positive high-voltage applications. It complements other devices like the TPS2492 by offering similar functionality with specific parameter variations suited for different voltage levels and protection requirements within the same product family ecosystem.

Replacement Considerations

Direct substitutes include the TPS2492PW and TPS2492PWR. Verify pinout compatibility and electrical parameter alignment, particularly regarding maximum voltage ratings and current limit programming ranges, before implementing any cross-replacement in existing designs.
