Dual-voltage supervisor in a tiny SOT-23-8
The MAX6392KA26+ is a multi-voltage supervisor monitoring two supply rails: one fixed at 2.63V, the other adjustable via external resistors. The 140ms minimum reset timeout gives the downstream processor enough time to stabilize after power-up before it starts executing code — that's long enough for most bulk capacitors to charge without the part holding the system in reset unnecessarily.
Industrial temperature grade and package
Rated for -40°C to 85°C ambient, this supervisor handles thermal swings in outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics.
Lifecycle and sourcing reality
No LTB or EOL notice to worry about for new designs.
