Supervisor with dual-polarity reset and 0.833V threshold
The MAX6841EUKD0-T: It provides both active-high and active-low reset outputs, giving the system designer flexibility to interface with either polarity of microcontroller or logic reset inputs. The push-pull output stage drives the reset line without needing an external pull-up resistor. The reset timeout is 150µs typical, which holds the reset state long enough for the monitored supply to stabilize before the processor starts executing code. Operating from -40°C to +85°C, this part suits industrial and commercial environments where the ambient temperature stays within that range.
Housed in a SOT-23-5 package (also designated SC-74A), the MAX6841EUKD0-T occupies a compact 5-pin footprint on the PCB. The surface-mount package is suited for automated assembly and reflow processes. With a single monitored voltage and a 0.833V threshold, this part is designed for low-voltage core rails — common in 1.0V to 1.2V digital supply monitoring where a precise undervoltage reset is needed. The 150µs timeout ensures the reset pulse is long enough for most microcontrollers to recognize it as a valid reset event.
