TPS25940LQRVCRQ1

Current Regulation/Management Overview

The TPS25940LQRVCRQ1 is an automotive-grade dual-channel hot-swap voltage controller designed for robust power distribution. It operates within a supply voltage range of 2.7 V to 18 V and supports channel currents from 600 mA to 5.3 A. The device features a typical on-resistance of 42 mΩ and low quiescent current of 202 µA. Certified to AEC-Q100 standards, it functions reliably across temperatures from -40°C to +125°C. Housed in a WQFN-20 package, it integrates short-to-battery protection and power-fail detection for secure system management.

Current Regulation/Management Feature Summary

• Integrated short-to-battery protection safeguards downstream loads against high-voltage faults.
• Dual-channel architecture enables independent control and monitoring of separate power rails.
• DevSleep support facilitates efficient power state transitions in automotive applications.

Current Regulation/Management Applications

• Automotive infotainment systems
• Body control modules
• Telematics units

Current Regulation/Management Procurement Notes

Verify the specific suffix 'LQRVCRQ1' matches the required package variant and temperature grade. Confirm AEC-Q100 qualification status aligns with target automotive reliability standards. Ensure input voltage specifications remain within the 2.7 V to 18 V operational window during all system states.

Current Regulation/Management Selection Notes

Select this component when dual-channel isolation and integrated short-to-battery protection are required. The 42 mΩ on-resistance suits applications prioritizing efficiency over ultra-low resistance alternatives. Verify that the WQFN-20 footprint fits the PCB layout constraints and thermal requirements.

Current Regulation/Management Part Context

This part belongs to the TPS25940-Q1 family of eFuses. It shares core functionality with other members but differs in channel count and specific pinout configurations. The Q1 designation indicates automotive qualification, distinguishing it from industrial variants like the TPS25940ARVCR.

Current Regulation/Management Replacement Considerations

Direct substitutes include other TPS25940-Q1 variants with matching channel counts. Verify pin compatibility before replacing single-channel parts like the TPS259270 or different series devices.
