Power management integrated circuits (PMICs) are incredibly useful and versatile devices. They enable electronic devices to control the flow of electricity, allowing them to run safely and efficiently. PMICs come in a variety of configurations to meet the needs of a wide range of applications, and supervisors are one of the most important types. These devices, such as the LTC2966CUD#PBF, offer precision voltage monitoring and much more.

What is the LTC2966CUD#PBF?

The LTC2966CUD#PBF is a precision supervisor, or voltage monitor, manufactured by Linear Technology. It has a -40°C to +105°C operating temperature range and is housed in a small 8-lead DFN package. It is designed to work with both bipolar and CMOS logic and features an internal voltage reference. It is capable of both simple reset and complex microprocessor reset functions.

Features

The LTC2966CUD#PBF offers a variety of features to meet the needs of many different applications. It has an input voltage range of 2.7V to 4.6V and can detect changes of less than 100mV. It also includes an adjustable reset threshold, manual reset input, active-high reset output, and programmable reset delay. Additionally, it has built-in reset glue logic to simplify complex reset design.

Applications

The LTC2966CUD#PBF can be used in a variety of applications, from mobile phones to medical systems. It can be used to protect systems from undervoltage and overvoltage by monitoring the power supply voltage. It can also be used for manual reset of a system in the event of a malfunction. In addition, it can be used in battery backup and load sharing applications.

Working Principle

The working principle of the LTC2966CUD#PBF is relatively simple. The device monitors the power supply voltage and compares it to the internal voltage reference. If the voltage drops below or rises above the preset threshold, the device will trigger a reset, which can be used to shut down the system if necessary. The device can be configured to issue either a short or a long reset depending on the needs of the application. Additionally, there is a manual reset input which can be used to manually reset the system.

Conclusion

The LTC2966CUD#PBF is a precision supervisor designed for a variety of applications. It features a wide input voltage range, an adjustable reset threshold, and manual reset input. It can be used for voltage monitoring in battery backup systems, load sharing applications, and more. Furthermore, it operates on a relatively simple principle, providing reliable protection against undervoltage and overvoltage conditions.
