What this supervisor does on the board
The MAX6836HXSD0+T is a simple reset/power-on reset IC from Analog Devices that monitors a single voltage rail and asserts a reset signal when the supply drops below its 1.665V threshold. It holds the reset output active for a minimum of 140ms after the rail returns above threshold, giving the downstream processor or FPGA time to initialize. The active high, push-pull output drives directly into the reset input of most microcontrollers and SoCs without needing an external pull-up resistor. Housed in a 4-pin SC-70-4 surface-mount package, it operates from -40°C to 85°C.
1.665V threshold — what it means for your rail
The 1.665V threshold monitors a single voltage rail.
Active high reset — check your processor's polarity
The reset output is active high.
Lifecycle and sourcing
The MAX6836HXSD0+T carries an Active lifecycle status from the manufacturer and is ROHS3 compliant.
