The LTC2912HDDB-1#TRPBF is a highly-configurable Power Management IC (PMIC) supervisor compliant with the Supervisors standard. It features an integrated low-power, 9-bit, voltage supervisor, voltage supervisor comparator, 1-Wire interface, and other features. The LTC2912HDDB-1#TRPBF is designed for applications with demanding environmental constraints and to meet maximum power efficiency targets.

Application Field

The LTC2912HDDB-1#TRPBF can be used in any type of system that requires reliable, accurate and efficient voltage monitoring and protection. It is commonly used in numerous applications such as automotive infotainment systems, medical portables, and consumer electronics. Additionally, it can be used in applications in industrial or temperature-control systems, personal navigation devices, and general-purpose industrial automation.

Working Principle

The LTC2912HDDB-1#TRPBF uses a unique 9-bit, programmable voltage supervisor for its primary feature. This supervisor is capable of monitoring up to 8 different voltages, this allows for more comprehensive system protection. It also features an integrated low-power, 1-Wire interface and doubles as a slave component for various 1-wire communication protocols. Additionally, the voltage supervisor has an internal delay circuit which can be configured to delay up to 5.6s when a threshold is violated.

The supervisor is also capable of sending an active-low output pulse in the event of an affirmative monitoring result. This feature allows the user to synchronize their system with the supervisor and can be used to control other parts of the system. The supervisor also has a power-good signal which remains low in the event that any of the monitored voltages have dropped below their specified threshold.

For additional protection, the LTC2912HDDB-1#TRPBF has the ability to monitor current levels and respond to overcurrent protection (OCP) conditions. It has the ability to monitor multiple load currents and is customizable with a wide range of OCP levels. This feature allows the system designer to add an extra layer of protection against potential catastrophic outcomes.

Conclusion

In conclusion, the LTC2912HDDB-1#TRPBF is a state-of-the-art PMIC supervisor that offers reliable system protection, flexible configuration options, and excellent power efficiency. It provides the user with the ability to monitor multiple voltages and current levels, allowing for comprehensive system protection, and the ability to configure the supervisor for their specific application requirements.
