Product details

Where it fits — temperature and package

The SC-70-3 package (SOT-323 footprint) is a compact three-pin surface-mount device — useful when board area is tight and you only need to babysit one supply rail. The open-drain output lets you wire-OR the reset signal with other supervisors or pull it up to a different voltage than VCC.

The RoHS status is non-compliant, which matters if your BOM requires full RoHS exemption compliance — verify your assembly house's policy on legacy lead-bearing finishes.

Frequently asked questions

What is the closest pin-compatible alternative to MAX6383XR23D3 in this component family?

The MAX6383 family includes multiple threshold voltage options in the same SC-70-3 package and pinout. The MAX6383XR23D1 is a sibling with a different threshold — verify your required threshold voltage before substituting. Both share the same active-low, open-drain output and 140ms timeout, so a threshold-matched variant is a drop-in replacement.

What is MAX6383XR23D3's listed type and reset configuration?

The device type is Simple Reset/Power-On Reset. The reset output is active low and open drain or open collector, meaning the output pulls low when the monitored voltage falls below the 2.31V threshold and releases (high-impedance) when the supply recovers and the 140ms timeout expires.
