What this nanoPower supervisor does
The MAX16074RS17D2+T is a single-channel voltage supervisor from Analog Devices' nanoPower series, designed for simple reset generation in low-power systems. It monitors a single supply rail and asserts a reset output when the voltage drops below a factory-trimmed 1.67V threshold. The reset output is active-low, open-drain, and remains asserted for a minimum of 34ms after the supply recovers, providing a clean startup hold for microcontrollers, FPGAs, and other logic devices. The part is rated for industrial temperature environments from -40°C to 85°C, making it suitable for outdoor telecom, factory automation, and battery-powered instrumentation where the ambient temperature can swing widely.
1.67V threshold — why it matters for your rail
The 1.67V threshold is set for monitoring low-voltage core rails common in modern SoCs and FPGAs — think 1.8V or 1.5V nominal supplies. At 1.67V, the supervisor trips before the core supply falls out of specification for most 1.8V logic, giving the downstream device a clean reset before data corruption occurs. This is a factory-programmed value; no external resistor divider is needed.
nanoPower series — built for battery life
The nanoPower series is optimized for ultra-low quiescent current, typically in the sub-1µA range, though the exact value is not listed here. This makes the MAX16074RS17D2+T a natural fit for battery-powered applications — portable medical devices, wireless sensor nodes, handheld instruments — where every microamp of standby current matters. The open-drain output also allows the reset line to be shared with other open-drain devices on a common pull-up resistor, saving a few more microamps compared to a push-pull output. The 4-UCSP package measures 1x1 mm. This is a wafer-level chip-scale package; the solder bumps are the terminals.
