Product details

The Maxim Integrated MAX6328XR31+T is a single-channel voltage supervisor that monitors a 3.08 V threshold rail and asserts a reset signal when the supply drops below that level. It is a Simple Reset/Power-On Reset IC — no watchdog timer, no manual reset input, just a clean reset pulse on power-up or brownout. The open-drain, active-low output lets you pull the reset line low to a microcontroller or FPGA reset pin, and the 100 ms minimum reset timeout gives the downstream device time to stabilize before release. The SC-70-3 package (SOT-323 footprint) keeps board area small — useful for space-constrained designs like sensor nodes or compact PLC modules.

ROHS3 compliant.

Frequently asked questions

Is MAX6328XR31+T obsolete or end-of-life?

No, the MAX6328XR31+T is currently Active in production with no end-of-life announcement. It is a standard production part suitable for new designs.

What is the output type and reset polarity of MAX6328XR31+T?

The output is open drain or open collector, and the reset is active low. This means the output pin sinks current to ground when a reset condition is detected, and it releases high through an external pull-up resistor when the supply is valid.

What is the reset timeout of MAX6328XR31+T?

The reset timeout is 100 ms minimum. After the monitored voltage rises above the threshold, the reset output remains low for at least 100 ms before releasing, ensuring the downstream device has time to stabilize.
