Introduction

TPS3780CDBVT is a family of ultra-low power supervisor and power-on reset integrated circuits (ICs) designed for system and power management applications. It is developed by Texas Instruments and the ICs have proprietary RST and RSTB open-drain signals which can be used for external reset. This IC comes in three package variations and offers superior protection against brownout, intermittent reset and active current conditions that are very common in large industrial systems and consumer applications. The TPS3780CDBVT is the industry’s smallest and the most power efficient supervisors and they employ advanced Bipolar-BiCMOS process which is proven to be reliable and efficient.

TPS3780CDBVT Application Fields and Working Principle

TPS3780CDBVT is ideal for use in large industrial systems, consumer applications and other power and system management applications. This IC can be used to control, monitor and protect system power management. Moreover, the RST and RSTB signals enable system reset and the low current consumption of this IC allows extended application operation, even in harsh operating conditions.The single power supply, low voltage variant of the TPS3780CDBVT is designed to pull its RSTb and RSTB signals low when the input voltage of the IC falls below its programmed threshold, indicating that a brownout condition or a power failure has occurred in the system. As a result, the IC will automatically reset the system, preventing any data loss or defects that would arise in a system operation. Furthermore, the IC employs a unique patented reset structure which allows it to identify and respond to conditions such as intermittent reset and active current conditions.The TPS3780CDBVT also has adjustable reset threshold voltage that helps to ensure that the system resets only when it is necessary. This can be done by adjusting the comparator’s threshold to the desired reset voltage level. Moreover, the reset control feature of the IC allows the user to determine when to reset the system. The reset control feature also allows for resetting the system in certain software applications with a simple trigger signal.The IC also provides an exact time-delayed reset with extreme accuracy, which is useful in measuring the power supply resolution of today’s integrated circuits. This time-delayed reset makes sure that the system performs predictably and that the correct operation is carried out by the integrated system components.

Conclusion

The TPS3780CDBVT family of ultra-low power supervisors can be used for system and power management applications and it is ideal for use in large industrial systems, consumer applications and other power and system management applications. It can be used to control, monitor and protect system power management and its adjustable reset threshold ensures that the system is reset only when necessary. The reset control feature and exact time-delayed reset of theIC are also useful and reliable features that make the TPS3780CDBVT an ideal solution for application operation and system management.
