PMIC - Supervisors is one of the most important electrical components in the modern electronic industry. The LTC690CN8#PBF is a power monitoring device within this family, designed to detect when the power supply is out of tolerance or out of voltage range. It monitors the various qualities of a power source and can then take action when it detects an irregularity. This device is considered reliable and easy to use, making it suitable for a wide range of applications. This article will explore the application fields and working principles of the LTC690CN8#PBF.

The LTC690CN8#PBF device has a wide range of applications, from automotive, industrial, and consumer electronic products. It’s designed to detect power disruptions in an efficient and reliable manner, according to the user’s control settings. This allows for steady operation in systems handling voltage fluctuations and other power irregularities, such as those experienced in cars, motorized tools, printers and other consumer electronics.

The reliable detection of a power disruption is largely thanks to the device’s comparator–based circuit design. In brief, the device includes two voltage comparators, one serving as a power-up monitor and the other a power-down monitor. Each monitor includes its own distinct user-configurable trip point, resulting in a wide range of protection options.

When the voltage reaches the power-up trip point, the device sends a logic high signal to the user’s system, notifying it that the power-up process is complete. The power-down trip point works similarly, however, in this case the device sends a logic low signal when the voltage drops below the set trip point.

In addition to those features, the LTC690CN8#PBF is equipped with an array of other features. These include adjustable time delays for the power-up and power-down events, as well as a power-good signal to indicate that the power supply is operating at its nominal voltage with no irregularities present. It also includes an open-drain RESET/MCLR input to manage the reset function.

The device also includes a watchdog timer, which is a system reset signal sent to the user’s system if the monitored power supply experiences a drop in voltage beyond the set limit. The timer can also be configured to reset the system if the power supply fails to return to its nominal voltage after an abnormal event or after a predetermined duration.

The LTC690CN8#PBF is also capable of handling both dual-supply and single-supply applications. In a single-supply system, it directly monitors the supply to the system, while in a dual-supply system, it monitors the output of the secondary supply, which powers the logic circuitry. This makes it a versatile device for a wide range of applications.

Overall, the LTC690CN8#PBF is an excellent device for monitoring power irregularities, and offers users a variety of protection features and adjustable functions to customize it to their needs. With its straightforward design and reliable detection capabilities, it’s an ideal solution for many different electronic applications.
