MAX6722UTVDD3+T Application Field and Working Principle
The MAX6722UTVDD3+T is a robust, ultra-low-voltage general-purpose supervisor from Maxim Integrated that is specifically designed to enable ultra-low power supplies. This supervisor provides assert and deassert for open-drain and push-pull reset outputs. It is ideal for applications that require ultra-low-voltage (1.1V to 2.1V) or a short supply reset rising time. The MAX6722UTVDD3+T also features a voltage-monitoring circuit for monitoring microprocessor core voltage.Application Areas:
The MAX6722UTVDD3+T addresses critical device reset, supply voltage monitoring and signal alerting tasks in ultra-low-voltage systems, such as those in automotive, industrial, medical and consumer applications, including:1. Automotive Applications: The MAX6722UTVDD3+T can be used in automotive applications to monitor and reset systems that may operate in extreme temperature and voltage ranges.2. Industrial Applications: The MAX6722UTVDD3+T is suitable for industrial applications such as motion control systems and PLCs, which require reliable reset and power-system monitoring.3. Medical Applications: The MAX6722UTVDD3+T is used in medical applications for resetting and power-system monitoring in ultra-low-voltage systems, such as portable electrocardiogram (ECG) machines and other life-monitoring devices.4. Consumer Applications: The MAX6722UTVDD3+T is suitable for resetting and power-system monitoring in portable, battery-operated systems, such as smart home and wearable devices.Working Principle:
The MAX6722UTVDD3+T is a supervisor that offers two reset outputs and two voltage-monitoring outputs. It has an active-high reset output (RESET_n) and an active-low watchdog reset output (WATCHDOG_n). The RESET_n output is asserted when the monitored voltage falls below the supervisor reset threshold and deasserted when the voltage rises above a higher level. The WATCHDOG_n output is asserted when a watchdog timeout occurs, and deasserted when the watchdog is pulsed. The MAX6722UTVDD3+T features a window comparator and a voltage-regulator-monitoring comparator to monitor power supply and voltage regulator performance. The window comparator monitors the power supply and provides two controls outputs, Wn_1 and Wn_2. Wn_1 is asserted when the monitored voltage falls below the lower threshold and deasserted when the voltage rises above the higher threshold. Wn_2 is asserted when the monitored voltage falls below the upper threshold and deasserted when the voltage rises above the lower threshold.The voltage-regulator-monitoring comparator is used to detect low-voltage conditions on the output pin of an external voltage regulator. It provides an active-low voltage-monitoring output (VM_n) that is asserted when the monitored voltage falls below the comparator threshold and deasserted when the voltage rises above the threshold. The supervisor reset output is also asserted if the VM_n output is asserted.The MAX6722UTVDD3+T can be used with either an external RC oscillator or an internal oscillator. The external oscillator enables a longer watchdog timeout period and the internal oscillator enables a shorter watchdog timeout period. In general, the MAX6722UTVDD3+T provides a simple and cost-effective solution for ultra-low-voltage monitoring, resetting, and power-system alerting in a variety of applications.
