The LTC2917IDDB-A1#TRMPBF is an integrated circuit (IC) that is part of a class of power management ICs (PMICs) known as supervisors. This article will explore the application field and working principle of the LTC2917IDDB-A1#TRMPBF.

The LTC2917IDDB-A1#TRMPBF from linear technology is an ideal power-supply supervisor providing twenty-four different voltage monitors, making it well adapted to monitor numerous supply voltages in a design. The board is designed to monitor supply voltages of between 0.59V and 2.075V, making it an ideal choice to monitor a wide range of applictions and power supplies. A salient feature of this PMIC is its ability to scan over 2-million-voltage points at a resolution of 0.005V. This makes it an ideal solution for applications that require the monitoring of complex power supplies.

The LTC2917IDDB-A1#TRMPBF is highly configurable, making it useful for a wide range of applications. The board supports programmable voltage monitoring threshold, allowing for the accuracy of the monitored voltage to be tailored to the specific requirements of a design. As well as being programmable, the supervisor is able to detect both rising and falling reaching thresholds as configured by the user. The voltage threshold registers are provided with non-volatile memory, providing an additional layer of flexibility.

Moreover, the board offers high performance with a fast response time and adjustable hysteresis, which is beneficial for designer looking to manage noise in power systems. The LTC2917IDDB-A1#TRMPBF also provides immunity to false triggering due to noise as well as brown-out detection.

The LTC2917IDDB-A1#TRMPBF is configured using a range of external capacitors and resistors. By adjusting the values of these components, the user is able to adjust the voltage threshold of the module. The board supports both active-high and active-low output configurations. Moreover, the board supports both latched and non-latched operation modes, allowing the user to select the most suitable mode for their design.

The LTC2917IDDB-A1#TRMPBF also provides power-on reset (POR) and power-down reset for the immediate reset of the system. The board also supports a range of alert and fault outputs as well as internal power loss detection that can be used to indicate a fault or alert condition. Furthermore, the board has open-drain friendly outputs and on-chip scaling resistors.

In conclusion, the LTC2917IDDB-A1#TRMPBF supervisor is an ideal PMIC for the monitoring of power supplies. With its programmable threshold, high accuracy, and adjustable hysteresis, the board is suitable for a wide range of monitoring applications. Moreover, the module provides additional features such as POR, power-down reset and fault/alert outputs that make it an ideal choice for designers looking for a comprehensive and highly configurable power-supply supervisor.
