Single-channel supervisor with an adjustable trip point
The MAX6302CUA+: The reset output is an Open Drain or Open Collector structure, so the pull-up resistor and logic-high voltage are set by the downstream circuit — not by the supervisor itself. The voltage threshold is Adjustable/Selectable via external resistors, giving the designer control over the trip point rather than being locked to a factory-programmed value.
2.8 ms minimum reset timeout — what it means for the boot sequence
After the supply rail returns above the threshold, the MAX6302CUA+ holds the reset output asserted for a minimum of 2.8 ms before releasing the processor to start code execution. This 2.8 ms window gives the power supply and oscillator time to stabilise before the CPU fetches its first instruction — a shorter timeout risks a brown-boot where the core starts before the rails are settled. The 8-TSSOP/8-MSOP package (3.00 mm body width) and the 8-uMAX/uSOP supplier package footprint suit compact single-rail designs where board area is tight.
