PMIC stands for Power Management Integrated Circuit which is an essential part of a system. It provides power to all of the ICs in the system and maintains a stable voltage to ensure its optimal performance. The LTC690CS8#TRPBF is a PMIC Supervisor developed by Linear Technology that provides robust system supervision and protection against overvoltage, undervoltage and overtemperature. It is an integrated system supervisor which monitors the input voltage, temperature and output voltage of the system.

The LTC690CS8#TRPBF combines a wide range of features in its small package. These features include two independent comparators, flexible reset outputs, manual and automatic reset inputs, programmable reset debounce, watchdog timer and thermistor temperature sensor inputs. It also provides power management for microprocessors, analog and mixed signal applications.

The LTC690CS8#TRPBF’s primary application field is in the automotive sector. It is used to monitor the system for overvoltage and undervoltage conditions, overtemperature events and fault code logging. These functions are essential for the safety and reliability of automotive systems. It is also ideal for use in industrial, medical, portable and consumer applications where system protection and reliable performance is important. The LTC690CS8#TRPBF has a wide temperature operating range of -55°C to 125°C.

The working principle of the LTC690CS8#TRPBF is simple but efficient. It continuously monitors the system’s voltage and temperature levels and generates an appropriate response based on the monitored parameters. It has two independent comparators that can be programmed to detect low or high threshold values. The comparators are connected to two globally-synchronized reset outputs which can be configured to generate a reset signal or set a fault flag. The watchdog timer is used to generate a reset signal if the system exceeds a predetermined time limit.

The LTC690CS8#TRPBF also has a programmable debounce feature. This feature is used to provide a time delay between the detected fault condition and the reset signal being generated. This allows the user to set a time limit for the system to gracefully reset itself in case of an abnormality. In addition, the LTC690CS8#TRPBF also has a manual and automatic reset input which can be used to force a reset signal in case of a fault. The thermistor temperature sensor input is useful for measuring temperature within the system.

The LTC690CS8#TRPBF is a highly reliable, low-power device which provides comprehensive protection to the system and prevents costly damage due to overvoltage, undervoltage and overtemperature. It is designed to meet the stringent requirements of automotive, industrial and consumer applications and its wide temperature operating range makes it suitable for use in extreme conditions. It is an essential component for the safety, reliability and performance of the system.
