One channel has a fixed 2.925V threshold; the second channel accepts an adjustable threshold set by an external resistor divider. The reset output is open-drain, meaning it can be wire-ORed with other reset sources on the same line. Reset timeout is adjustable via an external capacitor, giving the designer control over the power-up delay. The part operates from -40°C to 125°C and comes in a SOT-23-5 package. ## Threshold and reset behaviour The open-drain output can drive a pull-up resistor to various logic voltages. ## Lifecycle and sourcing No end-of-life notice or last-time-buy window has been announced. The part is ROHS3 compliant.","metaTitle":"MAX6420UK29+T Multi-Voltage Supervisor, 2.925V Threshold","metaDescription":"MAX6420UK29+T Multi-Voltage Supervisor monitors 2 channels, active-low open-drain reset, adjustable timeout, -40°C to 125°C, SOT-23-5.
