Active production — single-voltage supervisor in SOT-23-5
The MAX6823ZUK+T: The reset timeout is a minimum of 140 ms, giving the downstream processor or FPGA time to stabilize after the supply crosses the threshold. Housed in a SOT-23-5 (SC-74A) package, the footprint is compact enough for space-constrained boards in motor drives, base stations, or sensor nodes where a dedicated supervisor is preferred over a microcontroller-integrated brown-out detector.
Threshold and timeout — what they mean for the rail
The 2.32 V threshold is the falling-voltage trip point. If the monitored supply dips below 2.32 V, the reset output goes low and stays low for at least 140 ms after the supply recovers above the threshold. This prevents the load from seeing a glitched power-on sequence. Because the output is push-pull, no external pull-up resistor is needed — the output drives high or low directly. This saves a resistor and a PCB trace on the board. For a design that sees engine-bay heat or cold-soak at -40°C, the supervisor's timing stays within spec.
Analog Devices lists the MAX6823ZUK+T as active product status. It is ROHS3 compliant, covering the current EU RoHS exemption regime.
