Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'C03' corresponds to the required threshold voltages and delay settings, as these parameters define the functional behavior of this specific variant within the TPS38700 family. Confirm automotive qualification status (AEC-Q100) if required by your system specifications. Ensure the VQFN-24 package footprint matches your PCB layout constraints. Cross-reference the datasheet for exact electrical characteristics relevant to your design.

Power Supply Controllers, Monitors Selection Notes

Select this component when precise sequencing of multiple voltage rails is critical in automotive environments. The integrated watchdog and backup features reduce external component count. Consider the 2.2V to 5.5V input range compatibility with your system's main supply. The low quiescent current aids in energy efficiency. Verify that the specific threshold settings associated with the 'C03' suffix meet your monitoring requirements without needing external resistors.

Power Supply Controllers, Monitors Part Context

This part belongs to the Texas Instruments TPS38700 series, which are power-supply sequencers with IC support. The 'Q1' suffix indicates automotive grade qualification. The series is intended for systems requiring precise power sequencing and interfacing with multichannel voltage supervisors. Other variants in the series differ primarily in threshold voltages and delay times, packaged in VQFN-24.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes within the TPS38700 family include TPS38700C04NRGERQ1 and TPS38700C03NRGER, provided their specific threshold configurations match the design requirements. Verify pinout and package compatibility (VQFN-24) before substitution. Automotive grade equivalents must be confirmed for reliability standards.
