Supervisor IC for power-rail monitoring
The MAX6343RUT+T is a single-channel Simple Reset/Power-On Reset supervisor from Analog Devices, packaged in a SOT-23-6. The reset timeout is a minimum of 100ms, holding the reset signal low long enough for the downstream rail to stabilize before the processor or logic comes out of reset.
The SOT-23-6 (supplier device package SOT-6) is a surface-mount footprint with 0.95mm pitch typical for this class. The small outline suits space-constrained power modules or distributed reset monitoring on a main board.
