The DS1233MS-3+: A minimum reset timeout of 200 ms gives the downstream processor time to stabilize after the rail returns to tolerance before the reset is released.
Housed in an 8-SOIC (150-mil body width) package, it fits a standard surface-mount footprint with 1.27 mm pitch — no special layout requirements beyond the usual decoupling cap near the supply pin.
The DS1233MS-3+ monitors the supply rail and asserts a reset when Vcc falls below 2.72 V. This threshold is typical for 3.3 V logic systems where the processor needs a clean reset before the rail drops out of the valid operating range.
