2.93 V threshold — the rail supervisor for 3.3 V logic
This threshold is a direct fit for supervising a 3.3 V nominal rail, providing a clean reset to the processor or FPGA when the supply dips below the safe operating window. The active-low, open-drain output lets you wire-OR the reset with other supervisors or a manual reset button without contention.
10 ms timeout — why it matters for brownout recovery
For a typical MCU with a start-up time in the hundreds of microseconds, this margin eliminates the risk of the CPU trying to execute code before the oscillator and PLL have locked.
No official successor or second-source cross-reference is listed, so for dual-sourcing resilience, a parametric search for a supervisor with the same 2.93 V threshold, active-low open-drain output, and SOT-23-5 footprint would be needed.
