TPS2493PW

Overview

The TPS2493PW is a single-channel hot swap voltage controller manufactured by Texas Instruments. It operates within a supply voltage range of 9 V to 80 V and draws a typical operating supply current of 1 mA. The device is housed in a 14-pin TSSOP package designed for surface mount technology. It supports an extended operating temperature range from -40°C to +125°C. Key electrical features include programmable current limiting, power fail detection capabilities, and automatic retry functionality upon fault clearance.

Feature Summary

• Supports automatic retry functionality to restore power after transient faults without manual intervention.
• Integrates programmable current limiting to protect against overcurrent conditions during insertion.
• Includes dedicated power fail detection circuitry to monitor system integrity.
• Features input under-voltage lockout (UVLO) and overvoltage protection (OVP) for robust operation.

Applications

• General purpose hot swap controller applications
• High voltage power limiting systems
• Industrial equipment requiring safe board insertion

Procurement Notes

Verify the specific suffix 'PW' corresponds to the tube packaging format rather than the 'PWR' tape-and-reel variant. Confirm RoHS compliance status matches current manufacturing standards. Ensure the 14-TSSOP footprint aligns with the target PCB layout. Validate that the 9V to 80V input range meets the system's power requirements.

Selection Notes

Select this component when automatic retry behavior is required following a fault event, distinguishing it from latching variants like the TPS2492. Ensure the application voltage does not exceed the 80 V maximum rating. Consider the TSSOP-14 package constraints for thermal management and board space. Verify compatibility with external components needed for setting the programmable current limit thresholds.

Part Context

The TPS2493 belongs to the TPS249x series of hot swap controllers from Texas Instruments. It shares the same pinout and core architecture as the TPS2492 but differs in fault handling logic. While the TPS2492 employs a latching fault response, the TPS2493 utilizes an automatic retry mechanism. Both devices serve general-purpose power management roles in high-voltage environments.

Replacement Considerations

TPS2492PWR: Functionally similar but uses latching fault protection instead of automatic retry. Requires manual reset after faults.

FAQ

Does the TPS2493 automatically recover after a fault?

Yes, the device features an automatic retry function that attempts to restart the power sequence after a fault condition clears.

What is the maximum supply voltage for this controller?

The maximum supply voltage rating for the TPS2493 is 80 V.
