The push-pull output eliminates the need for an external pull-up resistor, simplifying the interface to the downstream MCU or FPGA reset pin. The 140 ms minimum reset timeout provides adequate hold time for most power-supply ramp sequences, ensuring the core logic starts from a known state. ## Temperature range and operating environment Rated for -40°C to 125°C ambient, this supervisor suits automotive under-hood, industrial motor-drive, and outdoor telecom equipment where the board sees wide thermal cycling. The SC-70-4 package keeps the footprint small enough for dense mixed-signal boards. ## RoHS status — a BOM constraint Marked as RoHS non-compliant, this part may require an exemption or a leaded-solder process. For RoHS-mandated builds, verify your assembly line's ability to handle SnPb finishes.","metaTitle":"MAX6387XS31D3 Multi-Voltage Supervisor, Active Low, SC-70-4","metaDescription":"MAX6387XS31D3 dual voltage supervisor from Maxim Integrated.
