LTC2911ITS8-3#TRMPBF

Power Management Integrated Circuits (PMICs) are key components for controlling and regulating the power supply for many systems, such as smartphones, computers, tablets, and other electronic devices. PMICs are used to provide adjustable and reliable power for diverse applications, including communications, manufacturing, medical, and automotive. PMICs also help control and regulate voltage and current, as well as implementing and optimizing other functions, such as battery level monitoring, over- and under-voltage protection, and thermal management. Supervisors are a specialized form of PMICs that are designed to monitor and control voltage levels and control the reset of a system when it detects a fault, trigger, or other event.

The LTC2911ITS8-3#TRMPBF is a precise, multichannel supervisor IC that can monitor three voltage or potential sources. It is suitable for precision power supply, microprocessor, and system monitoring and reset applications. The device can monitor voltages up to 5.25V with a fixed internal reference or external reference to monitor, prevent, and reset overvoltage, undervoltage, and asymmetry conditions. It includes an overvoltage/undervoltage (OVP/UVP) addressable timer and two independent open drain output pins (R1 and R2) to indicate status or reset a microcontroller or microprocessor.

The LTC2911ITS8-3#TRMPBF is suitable for various applications, including supervisory threshold monitoring, power monitoring, voltage supervisors, reset operations, and system reset tasks. It is suitable for applications such as digital cameras, tablet PCs, netbooks, computer monitors, LCD/OLED displays, set top boxes, cell phones, automotive systems, AC/DC adapters, motor controls, battery management, and industrial controls.

The working principle of the LTC2911ITS8-3#TRMPBF is straightforward. The device monitors three input voltages (VC1, VD2, and VD3) and an internal or external reference voltage (VL). The device then compares these voltages to their respective set thresholds and reports the results to the open-drain reset outputs. It also includes an adjustable overvoltage/undervoltage (OVP/UVP) addressable timer that delays reset or assertion of the R1 and R2 signals for a programmable duration, allowing for longer hold times. In addition, an adjustable timeout feature allows the resetting of the device after a set amount of time.

In summary, the LTC2911ITS8-3#TRMPBF is a precise, multichannel supervisor IC that is suitable for applications where precise power supply, microprocessor, and system monitoring and resetting is required. It can monitor voltages up to 5.25V with a fixed internal reference or external reference to monitor, prevent, and reset overvoltage, undervoltage, and asymmetry conditions, and has adjustable features to customize its behavior.
