MAX16025MAX16030 19-0525 Rev 3 1/07 Dual-/Triple-/Quad-Voltage, Capacitor- Adjustable, Sequencing/Supervisory Circuits General Description Features 2.2V to 28V Operating Voltage Range The MAX16025MAX16030 are dual-/triple-/quad-volt- age monitors and sequencers that are offered in a Fixed Thresholds for 3.3V, 2.5V, 1.8V, 1.5V, and small TQFN package. These devices offer enormous 1.2V Systems design flexibility as they allow fixed and adjustable 1.5% Accurate Adjustable Threshold Monitors thresholds to be selected through logic inputs and pro- Voltages Down to 0.5V vide sequence timing through small external capaci- 2.7% Accurate Fixed Thresholds Over tors. These versatile devices are ideal for use in a wide Temperature variety of multivoltage applications. Fixed (140ms min)/Capacitor-Adjustable Delay As the voltage at each monitored input exceeds its Timing respective threshold, its corresponding output goes Independent Open-Drain/Push-Pull Outputs high after a propagation delay or a capacitor-set time delay. When a voltage falls below its threshold, its Enable Inputs for Each Monitored Voltage respective output goes low after a propagation delay. 9 Logic-Selectable Threshold Options Each detector circuit also includes its own enable input, Manual Reset and Tolerance Select (5%/10%) Inputs allowing the power-good outputs to be shut off inde- Small, 4mm x 4mm TQFN Package pendently.
