Product details

What this reset IC does and where it fits

The push-pull, totem-pole output drives the reset input of an MCU, FPGA, or SoC directly — no external pull-up resistor needed. This part is built for the SC-70-3 (SOT-323) surface-mount footprint, which fits tight PCB layouts in industrial controllers, embedded systems, and portable equipment where board space is at a premium.

Active-high reset — what it means for your processor choice

This IC asserts a logic high on the reset output when the monitored voltage drops below the threshold. Not every processor expects an active-high reset — some want a low-going pulse. Check your target MCU or SoC reset polarity before committing the BOM. The push-pull output eliminates the external pull-up resistor, saving one component and one trace on dense boards.

100 ms timeout — standard window for most power-on sequences

Frequently asked questions

Does ADM1817-R22AKS-RL have an active high reset?

Yes, the reset output is active high. The output goes high when the supply voltage drops below the threshold and stays high for the 100 ms timeout period after recovery.

When sourcing ADM1817-R22AKS-RL, what's the closest functional second-source?

The ADM1817-R22ART-RL is a functionally identical sibling — same active-high reset, push-pull output, and 100 ms timeout — but packaged in a different reel format. For a pin-compatible alternative with a slightly longer 140 ms timeout, consider the ADM810TAKS-REEL.
