Power management integrated circuit (PMIC) are integrated circuit that are used to combine multiple power supply functions into a single package, thereby allowing increased power efficiency, faster power management and greater power control. These integrated circuits contain various electronic components and offer supervisors that help regulate currents and voltages to various components of an electronic system.

CAT1161WI-25-GT3 is one such supervisor which was designed by On Semiconductor, a leading manufacturer of power management solutions. The CAT1161WI-25-GT3 is a multi-level supervisor in a 20-pin SSOP package, designed for use in low-power, power-sensitive designs. As a supervisor, the CAT1161WI-25-GT3 monitors the power on reset (POR), supervisor reset (SR), and power-fail (PFI) levels of the system and activate various signals when these levels are crossed.

The CAT1161WI-25-GT3 is mainly used in the field of power management in electronic systems. This supervisor module can be used to help accurately monitor the power-on and power-off levels of an electronic system. Additionally, it can also be used to detect any sudden power-failures or short circuits in power supply, helping to protect the entire system from any potential damage. It is also used to automatically reset the system when the power comes back on, making sure the system remains stable even after a potential power surge.

The CAT1161WI-25-GT3 has a working principle very similar to other supervisor ICs. Its 20 pins provide a range of functions to control the power flow of an electronic system, including the input and output pins for the power reset, supervisor reset, and power-fail signals. The CAT1161WI-25-GT3 has an adjustable threshold voltage (VTH) set at 1.75V along with four adjustable hysteresis levels ranging from 0.15V to 0.85V. Once the VTH level is crossed, the supervisor sends a signal that is used to trigger various events, such as reseting the system or a power-down signal. Additionally, the CAT1161WI-25-GT3 also has an internal power-on reset (PoR) circuit to make sure that the system is reset whenever it is powered up.

The CAT1161WI-25-GT3 is a versatile supervisor IC, capable of monitoring the levels of various power-lines and triggering specific events. Its superior reliability has made it a preferred choice for low-power, power-sensitive designs. It is capable of providing accurate information about the power level fluctuations and also prevents any potential damage to the system caused by sudden power surges or short circuits. It is a vital power management IC and its wide range of applications makes it an ideal choice for most electronic systems and designs.
