This is the part for a multi-voltage board — FPGA core, I/O, and auxiliary — where a single supervisor IC replaces three discrete reset generators. The push-pull output eliminates the external pull-up resistor that open-drain supervisors need. ## Reset timing and temperature range Reset timeout is a minimum of 150 ms — long enough for the downstream processor to finish its power-on sequence before the supervisor releases the reset line. The push-pull output holds the reset state without a pull-up, simplifying the BOM on the processor's reset input. Surface-mount assembly is standard for this package class.","metaTitle":"MAX6743XKSDD3+ Multi-Voltage Supervisor, 3-Channel, SC-70-5","metaDescription":"MAX6743XKSDD3+ multi-voltage supervisor, 3 channels, active-low reset, push-pull output, 150ms timeout, SC-70-5.

This prevents the processor from starting execution before all supply rails are stable."},{"question":"Does the MAX6743XKSDD3+ need an external pull-up resistor on the reset output?","answer":"No. The output is push-pull (totem pole), so it actively drives the reset line high and low without an external pull-up.
