LTC695ISW-3.3#PBF

Power management integrated circuits (PMICs) are the devices of the future, offering superior performance in managing energy and energy use. PMICs offer engineers the ability to design innovative systems without worrying about system power. The LTC695ISW-3.3#PBF is a PMIC supervisor device specifically designed to manage power with ultra-low quiescent current. This PMIC easily meets load-transient and line-undervoltage protection requirements for a wide variety of applications.

Application Field

The LTC695ISW-3.3#PBF PMIC supervisor is used to provide system reset and supply monitoring. It is ideally suited for a broad range of applications, including microcontrollers, microprocessors, power supplies, portable devices, and battery powered systems. It can be used to manage and protect one or more outputs, providing numerous advantages like overcurrent, overtemperature, and overvoltage protection. It also offers additional features such as watchdog timer, manual reset, and an adjustable reset output delay.

Working Principle

The LTC695ISW-3.3#PBF PMIC supervisor functions by monitoring various parameters such as voltage, current, temperature, and others. It regulates the power to ensure system stability while preventing any overcurrent, overvoltage, or overtemperature issues. The device continuously reads the input voltage and compares it with the threshold voltage set on the device. If the actual voltage drops below the set threshold, the device triggers a reset, which powers off the system after a predetermined time of delay. This reset can also be triggered manually.

The device also provides overcurrent protection, which helps in protecting the system from overloading during peak hours. The overcurrent protection ensures that the system only uses the current required by the specified application. This helps in reducing the power consumption while at the same time ensuring the longevity and reliability of the system.

Furthermore, the LTC695ISW-3.3#PBF PMIC supervisor also has an adjustable watchdog timer, which can be used to monitor system performance. If the system does not respond in a predetermined time frame, the watchdog timer triggers a reset, thus shutting down the system. The device also has an adjustable temperature sensor which monitors the temperature of the system and can be used to shut down the system if the temperature exceeds a predetermined limit. This helps in protecting the system from overheating.

Conclusion

The LTC695ISW-3.3#PBF PMIC supervisor can be used for a wide variety of applications where power management and supply monitoring is required. It offers an adjustable reset output delay, an adjustable watchdog timer, and an adjustable temperature sensor, making it ideal for a range of applications. The device provides the necessary safety features to ensure optimal performance while minimizing power consumption. With its numerous features, the LTC695ISW-3.3#PBF PMIC supervisor can easily meet the power management needs of any system.
