LTC2938IMS#TRPBF Application Field and Working Principle LTC2938IMS#TRPBF (Linear Technology\'s Dual Power Monitor and System Supervisor) is a PMIC (Power Management Integrated Circuit) for monitoring and managing the power supply voltage of a system. More specifically, it is a programmable supervisor that can be used to detect multiple power supply conditions such as undervoltage (UV), overvoltage (OV), overtemperature, and brownout conditions in a system. It has many applications, such as computer and communication system power supplies, industrial and automotive systems, and even portable gadgets.The LTC2938IMS#TRPBF is a very versatile device that provides many features and customizable options. It comprises of a low-voltage monitor with voltage thresholds of 0.7V, 1.5V and 2.5V, which are programmed via external resistors. The device has a programmable timeout period between 1ms and 15.5s, and can be enabled through the manual enable pin or remotely via an I2C interface. It also provides a comparator output that can be used to detect slack in the system power supply voltage and alert the user. Additionally, it features an internal temperature sensor, allowing it to monitor the temperature of the system and provide protection against overtemperature. The LTC2938IMS#TRPBF device also provides many customizable features that can be configured via the I2C interface, such as the various output modes, the reset and alert output polarities, and the slew rate of the alert signal. This makes it ideal for applications where the user needs to customise the device according to their specific requirements. In order to ensure high reliability, the LTC2938IMS#TRPBF device incorporates advanced fault protection features that are designed to prevent system damage due to unexpected power supply conditions. These include power supply Reset (PSR), Overvoltage Protection (OVP), Undervoltage Protection (UVP), Overtemperature Protection (OTP), and Brownout Protection (BOP). Additionally, the device also has built-in safety features like the LED indicator, automatic system shutdown, and the I2C alert signal. In conclusion, the LTC2938IMS#TRPBF dual power monitor and system supervisor is a versatile and highly reliable PMIC for power management applications. It incorporates advanced protection features and customizable options, making it a great choice for complex industrial and automotive applications that require multiple power supply conditions to be monitored and managed.
