LM3722EM5-3.08/NOPB Application Field and Working PrincipleThe LM3722EM5-3.08/NOPB is a four to five-channel supervisor designed for use in consumer electronics industry and other applications. This integrated device offers a range of functionality that eliminate the need for complex and expensive discrete supervisory components. As a result, this supervisor is particularly useful for applications that require a high level of circuit protection and reliability.The LM3722EM5-3.08/NOPB is part of National\'s line of PMIC Supervisors. This integrated device is specifically designed to monitor multiple voltage levels and generate reset signals based on the monitored voltages. It includes a watchdog timer, an external reset input, an active-high reset output, external active-high and active-low pull up/pull down resistors, and an internal oscillator. The device also has an externally programmable watchdog timeout source and temperature-compensated monitoring.The main features of the LM3722EM5-3.08/NOPB include four or five monitor inputs with programmable Reset active/inactive levels; two output configurations; two optional temperature references; an adjustable voltage threshold; and programmable power sequencer. These features make the device ideal for ensuring safe operation of system components by detecting overvoltage, undervoltage, overcurrent and overtemperature conditions.The LM3722EM5-3.08/NOPB offers a range of reset configurations. When monitoring voltage levels, the device can be used to assert either a reset signal with an active-high output or an assert output with an active-low output. For overcurrent and overtemperature protection, the device can assert a reset signal with an active-low output.The LM3722EM5-3.08/NOPB provides a range of additional features that make it ideal for monitoring system components. The device includes adjustable voltage threshold and programmable power sequencer, enabling multiple voltage levels and reset configurations. The device also includes an external reset input and an optional temperature reference, allowing it to detect temperature changes and take appropriate action.The integrated device also includes an internal oscillator, enabling it to adjust its clock frequency based on environmental conditions. Finally, the device has an adjustable delay time, allowing it to wait for a predetermined amount of time before taking action.In summary, the LM3722EM5-3.08/NOPB is a four to five-channel supervisor designed for use in consumer electronics and other applications. This integrated device offers a range of features that make it ideal for ensuring safe operation of system components. It includes adjustable voltage threshold, programmable power sequencer, external reset input, temperature reference, internal oscillator and adjustable delay time. As a result, this supervisor is particularly useful for applications that require a high level of circuit protection and reliability.
