Product details

Voltage supervisor for a single 3V rail

The Maxim Integrated MAX6326XR30+T is a simple reset/power-on reset supervisor that monitors a single 3V supply rail. When the monitored voltage drops below the 3V threshold, it asserts an active-low reset output (push-pull/totem pole) and holds it for a minimum of 100ms after the rail recovers. This part is housed in a 3-lead SC-70-3 package (also SOT-323 footprint) and operates over -40°C to 85°C ambient temperature, making it suitable for industrial control, telecom, and general-purpose embedded systems where a clean power-on reset or brownout detection is needed.

3V threshold — selecting the right rail

The 3V threshold monitors a 3.0V nominal supply. The active-low reset output is compatible with most MCUs and SoCs that expect a low-true reset signal.

Lifecycle and sourcing reality

The MAX6326XR30+T carries an active lifecycle status and is ROHS3 compliant. This part is sourced through independent distribution and is quoted to order against an RFQ. For BOM planning, this is a stable, long-lifecycle part that will not force a redesign in the next few years.

Frequently asked questions

Does MAX6326XR30+T have an active-low reset output?

Yes, the reset output is active low with a push-pull/totem pole output stage. It asserts low when the monitored voltage falls below the 3V threshold and remains low for a minimum of 100ms after the voltage recovers.

Is MAX6326XR30+T a direct replacement for MAX6326XR27+T?

The MAX6326XR30+T and MAX6326XR27+T are pin-compatible and share the same package, reset polarity, and timeout. The only difference is the voltage threshold: 3V for the XR30 variant versus 2.7V for the XR27 variant. They are not direct replacements unless your monitored rail matches the threshold.

Can MAX6326XR30+T be used with 3.3V systems?

The MAX6326XR30+T has a 3V threshold. On a 3.3V rail, it will assert reset when the supply drops to 3V, which is a 300mV margin. This may be acceptable if the downstream logic has a higher brownout threshold, but for a 3.3V rail the MAX6326XR33+T (3.3V threshold) is the intended match.
