Supervisor IC for a single 1.58V rail
The MAX6383XR16D3: The reset output is Open Drain, allowing the pin to be pulled up to any voltage within the absolute maximum ratings of the device, which makes it compatible with mixed-voltage logic systems. With a minimum reset timeout of 140ms, the part holds the system in reset long enough for the monitored rail to settle and the oscillator to stabilize before the processor starts executing code.
SC-70-3 package and rework reality
Housed in a SC-70-3 (SOT-323) package, the MAX6383XR16D3 is a three-lead device with a compact footprint suited for space-constrained designs.
Temperature range and deployment context
The wide temperature range means the threshold accuracy and reset timeout are guaranteed across the full span, not just at 25°C, which matters when the supply rail drifts with temperature and the supervisor must still trip at the correct voltage.
