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.
No LTB or EOL notice to worry about for new designs.
The reset output is active low and can be configured as either open drain or push-pull. Open drain is useful when multiple supervisors share a common reset line; push-pull gives a clean rail-to-rail swing without an external pull-up resistor.
The MAX6392KA26+ monitors one fixed threshold at 2.63V and one adjustable channel. If your 2.5V core needs a supervisor, the adjustable channel can be set to 2.5V with a resistor divider. However, pin compatibility and exact function depend on the specific MAX6390 variant — check the respective datasheets for footprint and feature alignment before swapping.
The suffix +T typically indicates tape-and-reel packaging for automated pick-and-place assembly. The + version without the T suffix is shipped in bulk (tube or tray). Electrically they are identical.
