It is designed for systems that need to sequence or protect multiple power domains — think FPGA core and I/O rails, mixed-signal boards with separate analog and digital supplies, or any multi-voltage embedded controller. The reset output is push-pull, totem pole, so it drives the reset line directly without an external pull-up. ## Voltage thresholds and reset timing The three monitored thresholds are 1.11 V, 3.075 V, and an adjustable input that lets you set a third rail voltage with an external resistor divider. The reset timeout is a minimum of 150 ms. ## Package and temperature range Housed in an SC-70-5 (also known as SOT-353), this is a five-lead surface-mount package that fits tight layouts. The operating temperature range is -40°C to 85°C, covering industrial environments like factory-floor controllers, outdoor telecom cabinets, and automotive cabin electronics (non-engine bay). The supplier device package is SC-70-5, so verify your PCB footprint matches that standard. ## Lifecycle and sourcing For a BOM line that needs a multi-voltage supervisor, this part is a straightforward choice — no last-time-buy risk, no forced redesign.","metaTitle":"MAX6743XKTGD3 Multi-Voltage Supervisor, 3-Channel, SC-70-5","metaDescription":"MAX6743XKTGD3 multi-voltage supervisor monitors three rails with thresholds 1.11V, 3.075V, and adjustable.
