TPS25940AQRVCTQ1

Current Regulation/Management Overview

The TPS25940AQRVCTQ1 is a dual-channel hot-swap voltage controller designed for automotive applications, certified to AEC-Q100 standards. It operates within an input voltage range of 2.7 V to 18 V and supports current limits from 600 mA to 5.3 A per channel. The device features a typical on-resistance of 42 mΩ and draws a quiescent supply current of 202 µA. Packaged in a WQFN-20 format, it functions reliably across an extended temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Dual-channel architecture enables independent power distribution control for multiple loads.
• Integrated power-fail detection provides status indication during fault conditions.
• Automotive-grade qualification ensures reliability under harsh environmental conditions.

Current Regulation/Management Applications

• Automotive infotainment system power distribution
• ADAS sensor module power sequencing
• Vehicle body control unit load protection

Current Regulation/Management Procurement Notes

Verify the specific suffix 'TQ1' confirms the tape-and-reel packaging configuration and automotive grade designation. Ensure compatibility with the target PCB footprint for the WQFN-20 package. Confirm that the selected current limit settings align with the downstream load requirements to prevent nuisance tripping or insufficient protection margins.

Current Regulation/Management Selection Notes

Select this component when dual-channel isolation is required for automotive power buses. The wide input voltage range accommodates cold-load dump scenarios common in vehicle networks. Consider the low quiescent current for battery-backed systems where standby power consumption must be minimized while maintaining rapid response capabilities.

Current Regulation/Management Part Context

This part belongs to the TPS25940 family of hot-swap controllers manufactured by Texas Instruments. It serves as a specialized power management integrated circuit (PMIC) solution for robust load protection. The device integrates high-side switches with comprehensive monitoring features to safeguard sensitive electronics against overcurrent and short-circuit events.

Current Regulation/Management Replacement Considerations

TPS25940AQRVCRQ1 is a verified substitute offering identical electrical specifications and functionality, differing primarily in reel packaging quantity rather than performance characteristics.
