Power Management Integrated Circuits or PMICs are essential in the design of today\'s complex and power-intensive electronic devices. Supervisors are a type of PMIC that monitor the power supply and system conditions in order to maintain operation. Texas Instruments\' LTC2935IDC-3 is an example of such a device and is used to supervise and monitor the voltage, current and temperature in a quite diverse range of portable, battery-powered and industrial applications.

The LTC2935IDC-3 is a three-channel device featuring an overvoltage protection (OVP) output, a programmable over-voltage comparator and a high/low power supply detector. The OVP output can be set to remain active when the input voltage rises above a user-configurable threshold, and is then used to trigger an external circuit to shut down the system. The comparator output can be used to trigger an interlock circuit to prevent failure due to large input voltage swings. Finally, the high/low detector can be used to indicate when the power supply is within an acceptable range, providing plenty of choice for user-defined power management strategies.

In its standard form, the LTC2935IDC-3 is powered by a single 2.7V to 5.5V supply and also includes an undervoltage good (UVGOOD) output. This UVGOOD output is used to inform the system that the voltage supply is adequate, which can then initiate further operations. It is also suitable for use in extremely low voltage systems with a single supply as low as 1.8V.

The LTC2935IDC-3 also features a low quiescent current, high accuracy and fast settling time. This allows the device to accurately detect and protect against overvoltage and undervoltage events up to 1.8V. Additionally, its built-in temperature monitor allows the device to detect temperature changes that exceed the designed threshold.

The LTC2935IDC-3 is designed for use in a variety of applications, including portable and industrial electronics. It can be used to provide overvoltage protection to sensitive analog, digital and RF circuits, as well as to provide monitoring and signaling of temperature events. The device is also suitable for use in battery-powered applications and may be used as a battery charge indicator, providing a much needed safety feature in consumer electronics and medical devices.

The LTC2935IDC-3 also has the ability to measure the voltage, current and temperature in the system. This feature can be used to monitor system health and can help identify faults, ensuring optimal performance. The device\'s programmable thresholds allow the user to tailor their power management strategies to the unique requirements of the application.

The LTC2935IDC-3 is an ideal device for a range of systems in need of a reliable power management solution. It is designed for use in applications where power and accuracy are key to ensure a safe and reliable system. It is an excellent choice for both portable and industrial electronics.
