What the MAX6759UTTD0 is and where it fits
The Maxim Integrated MAX6759UTTD0 is a simple reset/power-on reset supervisor in a SOT-23-6 package. It monitors two voltage rails and asserts a reset signal when the monitored voltage drops below the 3.3 V threshold. The active-low, open-drain output holds the reset for a typical 20 µs timeout after the supply returns above threshold. This part is qualified to AEC-Q100, rated for -40°C to 125°C, making it a fit for automotive under-hood modules, industrial motor drives, and any 3.3 V system needing a dual-voltage window supervisor.
Key ratings and what they mean for the BOM
The 3.3 V threshold matches a 3.3 V supply rail. The 20 µs reset timeout is on the fast side.
Package and mounting
Surface-mount SOT-23-6, same footprint as many single-voltage supervisors. The supplier device package is also SOT-23-6, so no footprint mismatch. Standard reflow profile for SOT-23 applies.
Lifecycle and sourcing
The MAX6759UTTD0 is listed as Active with no end-of-life notice. It carries the Automotive, AEC-Q100 series designation. Note the RoHS status: non-compliant, so verify your assembly's RoHS exemption policy before specifying.
