2.625V threshold supervisor for processor power-rail monitoring
The MAX6444US26L+T: The 140ms minimum reset timeout holds the processor in reset long enough for the supply to stabilise after power-up, preventing code execution from a brown-out state.
Open-drain output and temperature range
The open-drain or open-collector output lets the reset signal wire-OR with other supervisors on the same pull-up rail — useful in multi-voltage systems where any fault should trigger a global system reset. Housed in the SOT-143-4 package, the part occupies a 2.9mm x 1.3mm footprint — a low-profile fit for space-constrained PCBs in portable instrumentation or sensor nodes.
