The MAX6720UTSVD3+T is an ultra-low-voltage microprocessor supervisory circuit designed to monitor up to three system power supply voltages. It asserts a system reset if any monitored supply falls below its factory-trimmed or adjustable threshold and maintains reset for a minimum timeout period after all supplies rise above their thresholds. This integrated dual/triple supervisory circuit significantly improves system reliability and reduces size compared to separate ICs or discrete components.
Key electrical specifications include monitoring primary supply voltages (VCC1) from 1.58V to 4.63V and secondary supply voltages (VCC2) from 0.79V to 3.08V. An externally adjustable RSTIN input option allows monitoring of a third supply voltage down to 0.62V. The device guarantees correct reset output logic state when either VCC1 or VCC2 remains greater than 0.8V. It offers a reset timeout period of 140ms minimum and operates with a low supply current of 14µA typical at 3.6V.
This supervisory circuit is available in a compact SOT-23-6 package, suitable for surface mount applications. It operates over a temperature range of -40°C to +85°C. The MAX6720UTSVD3+T is designed for applications requiring reliable power supply monitoring in multivoltage systems, including telecom/networking equipment, computers/servers, portable/battery-operated equipment, and industrial applications.
