A PMIC – Supervisors, also known as a power management IC, is an integrated circuit that is designed to efficiently manage the power consumption of electronic circuits using a combination of electrical and thermal techniques. Such ICs provide voltage regulation, power sequencing, current monitoring, and over-temperature protection for the electronic circuit. Among them, the TC54VC4102EMB713 is an arbitrarily programmable, multi-threshold voltage supervisor IC with an adjustable watchdog timer. It is primarily designed to provide over- and under-voltage protection for applications that require multiple supply voltages and require multiple reset thresholds.

TC54VC4102EMB713 Application Fields

The TC54VC4102EMB713 is ideal for use in a wide range of applications on the industrial market. For example, they are suitable for use in various industrial automation equipment, such as motor controllers and programmable logic controllers. It can also be used in commercial power systems as well as consumer electronic products, including TV, digital video recorders and DVD players.

TC54VC4102EMB713 Working Principle

The TC54VC4102EMB713 is easy to program, with an adjustable digital threshold as well as watchdog timer. It also has comparators and latch circuitry, which are essential to its operation. The supply voltage to the device is fed through an input comparator, which is compared to the pre-programmed digital threshold. When the supply voltage rises above the set threshold, the over-voltage comparator will raise a reset signal. Conversely, when the supply voltage drops below the set threshold, the under-voltage comparator will raise the reset signal. The reset output is activated once both the over-voltage and under-voltage signals are detected.

The TC54VC4102EMB713 also features a watchdog timer. The user can program the watchdog timer to reset the system if no inputs are detected within a certain period of time. This prevents system lock-ups from occurring due to unexpected errors or malfunctions. The device also has adjustable filter time, so the user can choose to slow the reset transition time if needed. This can be useful in situations where the reset needs to be delayed to safely power down the system.

The TC54VC4102EMB713 can also be programmed to detect short circuits and overheating, both of which are common in industrial applications. When it detects a short circuit, it can shut off the power to the system and prevent damage. Similarly, when it detects overheating, it can control the system\'s power output to prevent further damage.

Conclusion

The TC54VC4102EMB713 is a powerful and versatile PMIC – Supervisors device, which can be used in a wide range of applications in the industrial and consumer markets. Its adjustable threshold, watchdog timer, and other features make it ideal for use in applications that require multiple reset thresholds and over- and under-voltage protection. Its ability to detect and protect against short circuits and overheating also makes it an excellent choice for any system that needs additional power management.
