Procurement Notes

Verify the specific suffix G-CTR indicates tape and reel packaging when ordering. Confirm AEC-Q100 qualification status for automotive projects. Check RoHS compliance documentation for environmental regulations. Ensure the SSOP-6 footprint matches your PCB layout constraints. Validate the adjustable voltage range against your circuit design needs before procurement.

Selection Notes

Select this component when dual-channel voltage monitoring is required with high precision. Consider the adjustable nature of the detection voltage for custom threshold settings. Evaluate the low static current benefit for battery-powered or energy-sensitive applications. Ensure the 40 V maximum input voltage aligns with your system's power rails. Verify thermal performance within the specified operating temperature range.
