The active-low, push-pull output drives directly into the reset input of an MCU, FPGA, or SoC without an external pull-up. The 140 ms minimum reset timeout gives the main supply and crystal oscillator time to settle before the system boots. Housed in a SOT-23-6 package (supplier device package SOT-6), it is a surface-mount part rated for the -40°C to 85°C industrial temperature range. The part is ROHS3 compliant and carries an active lifecycle status — no end-of-life notice, suitable for new designs and ongoing production.","metaTitle":"MAX6449UT46L+T Multi-Voltage Supervisor, Active Low Reset","metaDescription":"MAX6449UT46L+T multi-voltage supervisor from Analog Devices.
