Product details

3.08V threshold supervisor in SC-70-3

The MAX6383XR31D1 is a single-channel voltage supervisor from Maxim Integrated, monitoring a 3.08V threshold rail with an active-low, open-drain reset output. The 1ms minimum reset timeout holds the micro in reset long enough for the supply to stabilise after a brownout or power-up — no external timing capacitor needed.

Field-swap fit: SC-70-3 and pinout

The open-drain output lets you wire-OR the reset signal with other supervisors or pull it up to a different logic voltage than the monitored rail.

Frequently asked questions

What is the reset timeout for MAX6383XR31D1?

The reset timeout is 1ms minimum. This internal delay prevents the micro from running during the supply ramp — no external capacitor sets the period.

Can MAX6383XR31D1 replace MAX6383XR29D1?

The two parts share the same package (SC-70-3), output type (active-low open drain), and reset timeout (1ms min). The difference is the threshold: 3.08V for the XR31D1 versus a lower threshold for the XR29D1. If your design monitors a 3.08V rail, the XR31D1 is the correct fit; the XR29D1 trips at a different voltage and would not protect the same supply.
