The MAX16029TG+ is a quad voltage, capacitor adjustable, sequencing/supervisory circuit in 24 pin TQFN package. It allows fixed and adjustable thresholds to be selected through logic inputs and provide sequence timing through small external capacitors. This device is typically used in wide variety of multivoltage applications where voltage at each monitored input exceeds its threshold, its corresponding output goes high after a propagation delay or a capacitor-set time delay. When a voltage falls below its threshold, its respective output goes low after a propagation delay. The independent output of detector is available with open-drain configuration capable of supporting voltages up to 28V thereby allowing it to interface to shutdown and enable inputs of various DC to DC regulators. It also includes a reset function that deasserts only after all of the independently monitored voltages exceed its threshold. The reset timeout is internally fixed or can be adjusted externally.
