Integrated circuits (ICs) have revolutionized the electronics industry and are used in virtually all electronic applications. Integrated circuit supervisors are Specialized ICs that serve the specialized function of monitoring supply voltages and alerting a system when the parameter values exceed normal operating range. The LM3724EM5X-4.63 IC is a low voltage, low output voltage supervisor based on the L3724EM family of Supervisors from TI. It provides a regulated 4.63V supply output and provides a wide variety of features and protections. This article explores the application field and working principle of the LM3724EM5X-4.63 supervisor IC.

The Application Field of LM3724EM5X-4.63 Supervisor IC

The LM3724EM5X-4.63 supervisor IC has many features designed to provide reliable protection to electronic systems. It can be used in a wide variety of applications, including microprocessor-based systems, precision measurement and control systems, embedded systems, and automotive applications. It is well-suited for high-temperature and harsh environment applications and can operate across a wide temperature range. In addition, it has low power consumption and is resistant to shocks, vibrations, and other environmental stressors. The device also features an internal watch-dog timer, as well as an adjustable reset output voltage and a bus lock output.

Working Principle of LM3724EM5X-4.63 Supervisor IC

The LM3724EM5X-4.63 supervisor IC is composed of a watchdog timer and a power sequence manager (PSM). The watchdog timer monitors the system activity and can reset the system if it does not receive a regular clock signal. The PSM controls and monitors the system power supply state and can also reset the system if it detects an undesired power event. The PSM also provides an adjustable reset output voltage (VOR) and a bus lock output, giving the user the option of connecting two controllers together and signaling the start or end of a power event.

The device also has an internal voltage comparator and a voltage reference. The comparator is used to compare the supply voltage to the reference voltage and if the supply voltage exceeds the reference voltage, the comparator will trigger the reset output and the bus lock output, signaling the start of a power event. If the supply voltage drops below the reference voltage, the comparator will reset the system and the output voltage will be adjusted to the desired level.

The LM3724EM5X-4.63 supervisor IC also has a number of built-in protection features to protect the system from over-voltage and reverse-voltage conditions. It includes an overvoltage lockout (OL) to protect the system from overvoltage and overcurrent conditions, and a reverse voltage lockout (RVL) to provide additional protection from reverse voltage conditions. The device also includes a thermal shutdown feature that protects against faults caused by thermal effects. Finally, the device can be programmed to enter sleep mode when not being used to conserve power.

Conclusion

The LM3724EM5X-4.63 supervisor IC is an integrated circuit supervisor based on the L3724EM family of Supervisors from TI. This IC provides a regulated 4.63V supply output and features a wide variety of features and protections, making it an ideal solution for embedded and automotive applications. The device is composed of a watchdog timer and a power sequence manager (PSM) and has a number of built-in protections, such as an overvoltage lockout, reverse voltage lockout, and thermal shutdown feature. In addition, the IC has a highly adjustable reset output voltage and a bus lock output, making it an excellent choice for applications that require reliable protection from over-voltage and reverse voltage conditions.
