Product details

Single-supply supervisor for 3.3V rails

The ADM825SYKSZ-R7: Both an active-high and an active-low reset output are available, each push-pull, so the same IC can drive a microcontroller's reset pin (usually active-low) and also signal an enable line or an interrupt controller that needs the opposite polarity — no external inverter needed. The 140ms minimum reset timeout holds the processor in reset long enough for the supply to stabilise after a power-on or a brownout recovery, which covers the start-up settling time of most 3.3V rails feeding a Cortex-M or similar MCU.

Industrial temperature range and small footprint

The 0.65 mm pin pitch is hand-solderable with a fine tip, so field rework is practical. At the 5 µA typical supply current, self-heating is negligible even in still air.

Active production and compliance

ROHS3 compliant with no exemptions — no lead, mercury, or phthalates in the bill of materials, which simplifies EU and UKCA market entry without a certificate-of-compliance chase.

Frequently asked questions

What is the closest functional second-source to ADM825SYKSZ-R7?

The ADM825ZYKSZ-R7 is the closest sibling — same threshold voltage (2.93V), same reset polarity options (active high/active low), same push-pull outputs, same 140ms minimum timeout, and same SC-70-5 package. The only difference is the suffix, which typically indicates tape-and-reel vs tube or tray packaging. It will drop into the same PCB footprint without any board change.

What is ADM825SYKSZ-R7's reset polarity?

The ADM825SYKSZ-R7 provides both active-high and active-low reset outputs, each push-pull. This means a single IC can drive both a microcontroller's active-low reset pin and an active-high enable line without external logic.
