Note that the part is listed as RoHS non-compliant, so it does not carry the lead-free / RoHS marking — confirm your assembly's exemption or waiver before specifying this order code for a RoHS-required BOM line.","metaTitle":"MAX6721UTLTD3-T Multi-Voltage Supervisor, SOT-23-6","metaDescription":"MAX6721UTLTD3-T multi-voltage supervisor monitors two rails at 3.075V and 4.625V.
