Single-channel battery backup supervisor in SOT-23-6
The Analog Devices MAX6364LUT31+T is a single-channel battery backup circuit that monitors a single voltage rail and holds the reset output low when the supply drops below the 3.08 V threshold. The reset remains asserted for a minimum of 150 ms after the voltage recovers, giving the downstream processor time to initialize cleanly. The push-pull, totem-pole output eliminates the need for an external pull-up resistor. Housed in a 6-pin SOT-23 package, it fits tight board layouts where a dedicated supervisor is required for battery-backed SRAM, RTCs, or microcontroller power-fail detection.
3.08 V threshold — what it means for your rail
The 3.08 V threshold is fixed and not adjustable. When the rail dips below 3.08 V, the reset output goes active low.
150 ms reset timeout — why it matters
The 150 ms minimum reset timeout gives the processor or memory enough time to complete a reset sequence before the supervisor releases the reset line. A shorter timeout risks the processor starting before the supply is stable; a longer timeout delays system startup. This 150 ms figure is a common middle ground for most MCUs and SRAM controllers.
Active production, no obsolescence risk
The part is ROHS3 compliant. No last-time-buy or end-of-life notice is on record.
