Key Featrues
Factory-Set Reset Threshold Voltages - The MAX6381–MAX6390 series offers reset threshold voltages ranging from +1.58V to +4.63V in approximately 100mV increments. This precision ensures reliable monitoring of power supply voltages, enhancing system stability and reducing the risk of malfunction in low-voltage applications.
Low Power Consumption - With a supply current of only 3µA at +1.8V and 6µA at +3.6V, these supervisory circuits are highly energy-efficient. This low power consumption makes them ideal for battery-powered portable equipment, extending battery life and improving overall efficiency.
Multiple Reset Timeout Periods - Seven reset timeout periods ranging from 1ms to 1200ms are available, providing flexibility in system design. This feature allows for customization based on specific application requirements, ensuring optimal performance and responsiveness in critical µP and µC power monitoring systems.
Reset Output State Guaranteed Down to VCC = 1V - The reset output remains valid even when VCC drops to 1V, ensuring reliable operation during power supply fluctuations. This feature enhances system robustness, particularly in environments with unstable power conditions or during power-up/power-down sequences.
Negative-Going VCC Transient Immunity - The supervisory circuits are designed to withstand negative-going VCC transients, providing added protection against voltage spikes or dips. This immunity improves the reliability and durability of the system, especially in industrial or automotive applications where power supply disturbances are common.
