PMIC - Supervisors

The TC1271ASVCTTR is a type of Supervisor, a product of Texas Instruments. Supervisors are among the most popular components of power control devices. It is typically used for providing system control and reset signals for applications such as on-off control and reset protection, providing voltage monitoring for over or under voltage conditions. This particular device offers adjustable UVLO (Under Voltage Lock Out) thresholds, and low power consumption, making it popular for a wide range of applications.

Application Field

The TC1271ASVCTTR is usually used in a wide range of power control applications. Examples of this are the protection of power supplies and DC/DCconverters, personal computers, automotive batteries, and energy-saving lighting systems. In general, any system that requires protection against over current, over voltage, under voltage and reset will likely benefit from using the TC1271ASVCTTR.

Working Principle

The TC1271ASVCTTR supervisor is a low power consumption device that operates through the detection of an under voltage event. It is an integrated circuit that includes a reset generator, a power on reset generator, a power down reset generator and an under voltage lockout circuit. This makes it an ideal choice for providing system resets and over/under voltage conditions for power supplies and DC/DC converters, as mentioned before. When the under voltage event is detected, the device outputs a reset signal, which will either power down the converter, or turn it off. This reset stability is maintained by a low quiescent current, making it suitable for applications where long-term protection is required.

Conclusion

The TC1271ASVCTTR supervisor is an ideal device for any power control applications. With its adjustable UVLO thresholds and low quiescent current, it can provide excellent protection against over current, over voltage, under voltage and reset events. This makes it a reliable, cost-effective choice for a wide range of applications in the fields of power supplies, DC/DC converters, personal computers, automotive batteries and energy-saving lighting systems.
