The reset output is active high with a push-pull, totem pole stage, so it drives a logic high during power-up, brown-out, and manual reset conditions. Housed in a compact SC-70-3 (SOT-323) package, this part suits space-constrained boards in industrial control, telecom, or embedded systems where a dedicated supervisor is needed without the overhead of a multi-voltage sequencer.
2.31 V threshold — the so-what for your rail
The 2.31 V threshold is the trip point at which the reset asserts.
Active high output — confirm your logic polarity
The reset output is active high, meaning the pin goes high when the monitored voltage falls below threshold and stays high for the 100 ms timeout after the voltage recovers. Most microcontrollers expect an active low reset, so verify your processor's reset polarity before specifying this part. If your design uses an active low reset, the ADM1817-R23AKS-RL would need an inverter or a different part number in the ADM1817 family.
SC-70-3 package — board area and assembly
The SC-70-3 (SOT-323) package is a surface-mount package with three leads.
