Power management integrated circuits (PMICs) are integrated circuits designed to monitor, control and protect a variety of power supply systems. PMICs can provide enhanced safety features, efficient power delivery, programmable output supply voltages, power cycling, overload protection, and other features such as integrated low-noise voltage regulators and converters. Supervisors are a type of PMIC designed to monitor power supply states and inputs and to provide feedback to control circuitry. LP3470M5-3.08/NOPB is an example of a supervisor IC.

The LP3470M5-3.08/NOPB is part of the Texas Instruments LP3470 family of voltage supervisor ICs, which provide adjustable reset, clock, and power-fail (PFI) functions. The IC is a low-power, 3.08V-output voltage supervisor with adjustable reset timeout. It is intended for applications where reliable power monitoring and management is necessary, such as server and networking equipment, disk drives, consumer electronics, and automotive systems. This IC has an integrated ultra-low-power reset timing circuit, allowing it to be used in a wide variety of applications.

LP3470M5-3.08/NOPB provides adjustable reset, clock, and power-fail (PFI) functions. The adjustable reset timeout allows the circuit to remain in reset until a specified amount of time has elapsed, after which the reset will be deasserted. The clock function provides a stable clock output with an adjustable frequency range of 1kHz to 2MHz. The PFI output provides an active-low signal when the input voltage drops below the control voltage.

The power-fail (PFI) output of the LP3470M5-3.08/NOPB has a built-in 1.25V voltage reference, allowing it to easily monitor the power supply voltage. It also includes an adjustable watchdog timer which can be used to reset the system if the input voltage goes below a specified level for an extended period of time. The output can be configured as an open-drain, push/pull, or an open-drain with Schmitt trigger for increased noise immunity.

The LP3470M5-3.08/NOPB is a very versatile supervisor IC that is able to monitor the power supply and inputs, provide feedback to control circuitry, detect power failure and reset the system if necessary. It provides adjustable reset timeout, adjustable clock frequency, and active-low power-fail output with built-in voltage reference and adjustable watchdog timer. It is designed to meet the demanding requirements of a wide range of applications and is suitable for use in server and networking equipment, disk drives, consumer electronics, and automotive systems.
