4.38V threshold supervisor for a single supply rail
The MAX6343MUT+T is a simple reset/power-on reset supervisor from Analog Devices, monitoring a single voltage rail with a 4.38V threshold. When the monitored supply drops below that threshold, the active-low open-drain output asserts reset and holds it for a minimum of 100ms after the rail recovers — long enough for the downstream MCU or DSP to complete its power-on reset sequence.
Active lifecycle and sourcing posture
The part is ROHS3 compliant. For current pricing and availability, submit an RFQ; we source through independent distribution and confirm lot traceability and manufacturer warranty at quote time.
Housed in a SOT-23-6 (SOT-6 supplier package) surface-mount package. The 100ms minimum reset timeout is a fixed internal delay; no external capacitor is needed to set the timeout.
