PMIC (Power Management Integrated Circuit) includes several power-supply controllers, monitors, regulators, supervisors, transducers, and converters which are manufactured in a single chip. The LTC2921IGN-2.5#TRPBF is a power-supply controller belonging to this class of PMICs. This IC operates from a single 2.5V power supply and integrates power-supply control functions required to monitor, control, and regulate digital supplies.

The LTC2921IGN-2.5#TRPBF consists of a low-dropout linear regulator, an adjustable voltage detector, a programmable timer and a temperature-to-voltage converter on a single monolithic IC. It provides stable 2.5V regulation, with current up to 250mA, while also monitoring and controlling overvoltage and undervoltage conditions. The timer can be used to implement a variety of time-controlled functions such as time-delay power-on reset and overtemperature warning sign up to 45.5s timeout. The temperature-to-voltage converter provides a temperature-sensitive output for temperature monitoring.

The LTC2921IGN-2.5#TRPBF is most commonly used in notebook and laptop computers, cellular telephones, digital cameras, and other battery-powered portable equipment. It provides a variety of power-supply control functions to monitor and regulate the applied power sources to improve system performance and stability. It ensures that the power supply does not run at abnormal voltages, thus avoiding potentially damaging voltage excursions that could otherwise destroy the equipment. It can also be used to turn on the power supply at predetermined times and shut it down at predetermined time intervals. This function can be used to save power and reduce heat buildup inside the device while ensuring efficient power delivery at the same time.

The LTC2921IGN-2.5#TRPBF is an ideal solution for power-supply monitoring, control and regulation in portable instruments. Its wide input voltage range, low dropout linear regulator, adjustable voltage detector, programmable timer, and temperature monitor make it well suited for a variety of power-supply control applications. In addition, its small size and low power consumption also make it a great choice for mobile applications.
