Housed in a 5-pin SOT-23-5, this part is small enough for dense layouts. The SOT-23-5 has a clear pin-1 orientation mark.
The wide temperature span means the reset threshold and timeout stay within spec across the full range — no surprise resets in a cold start or a hot engine bay.
No end-of-life notice, no last-time-buy pressure. For new designs, this part is a safe choice.
The reset timeout is a minimum of 140ms. This means the reset output stays low for at least 140ms after the supply voltage rises above the 4.63V threshold, giving the downstream IC time to stabilize its internal state.
The reset output is active low. The part asserts a logic low on the reset pin when the monitored voltage falls below the threshold, and releases it high after the timeout period.
The ADM823SYRJZ-R7 is a functional equivalent with the same reset type, output, timeout, and package, but with a different threshold voltage (not 4.63V). For a direct threshold match, the ADM823RYRJZ-R7 is the peer to compare — same 4.63V threshold, same active-low push-pull output, same SOT-23-5 package. Verify the threshold before substituting.
