3.08V threshold supervisor in a 4-pin SC-70
The MAX6384XS31D3+T is a single-channel voltage supervisor from Analog Devices, monitoring a 3.08V rail with an active-low, push-pull reset output. It asserts reset when the monitored voltage drops below the threshold and holds it low for a minimum of 140ms after the rail recovers, providing a clean power-on reset signal for microcontrollers, DSPs, or other logic devices. Housed in a 4-pin SC-70-4 (SOT-343) surface-mount package, it fits into dense PCB layouts where board space is at a premium.
Active production with full compliance coverage
It is ROHS3 compliant, meeting the latest European Union directive for restriction of hazardous substances. No additional compliance documentation gaps exist for global shipping into regulated markets.
Reset timing and output drive for processor interfacing
The push-pull output stage drives the reset line directly without an external pull-up resistor, saving one component and one PCB trace. The active-low reset polarity matches the standard reset input on most ARM Cortex-M, PIC, and AVR microcontrollers, so the connection is a direct wire from the supervisor output to the processor's RESET pin. The single-voltage monitoring covers one supply rail; for multi-rail systems, additional supervisors or a multi-channel device would be needed.
