Power management integrated circuit (PMIC) refers to an integrated circuit that combines several power management functions such as voltage compensations, switching, and energy scavenging. Many PMICs are tailored for specific applications such as portable electronics, automotive, and the industrial markets. Supervisors, a subset of PMIC, are responsible for reset, voltage monitoring, and watchdog functions. Within the supervisors category, CAT1026WI-28-GT3 stands out as an industry-leading IC with robust features and high reliability.

CAT1026WI-28-GT3 is a low voltage supervisor designed to monitor multiple voltages and support integrated reset, watchdog, and manual reset. It has an auto-power on feature from either vcc or external reset source, as well as a manual reset input. This PMIC supervisor employs an internal voltage monitor for detecting core voltage variations, and also offers optional manual reset functionality for resetting the system during software debug. When used in low voltage applications like portable electronics, CAT1026WI-28-GT3 provides high accuracy and fast response times.

Feature-wise, CAT1026WI-28-GT3 offers a temperature coefficient of 0.01 %/K, making it incredibly accurate over temperature; a reset assertion trip point range of 0.6 V to 3.63 V; and a reset de-assertion trip point range of 1.25 V to 4.32V. In addition, this IC offers a wide input voltage range of 2.7V to 6.6V, allowing for flexibility in different applications. Last but not least, the IC has a watchdog output to monitor system activity, in case the processor does not resume from sleep mode.

In terms of applications, CAT1026WI-28-GT3 is popularly used in portable devices such as tablets and cell phones, as well as consumer electronics, industrial systems, and automotive electronics. Its ability to reduce the number of external components makes it an ideal choice for many end-applications. For example, this IC can be employed in a PC system to monitor the system voltage. It can be used in an automotive system to detect and control the voltage levels of the electric motor and the power converter, and also to reset the system in case of failure. When connected to a system, CAT1026WI-28-GT3 provides a robust and reliable system oversight.

The working principle of the CAT1026WI-28-GT3 is to monitor the power supply voltage and to generate a wired signal, which can then be used to reset the system. The IC will first activate its internal voltage monitor circuit to detect any changes in the input voltage. If the voltage level exceeds a predetermined trip point, the supervisor will signal the system to assert a reset sequence. The supervisor circuit also contains a timer circuit which is used to continuously monitor the system\'s activity. If the pre-defined time has elapsed and the system does not resume back to normal operation, the supervisor will signal a timeout reset.

In summary, the CAT1026WI-28-GT3 is an advanced low voltage supervisor with a wide input voltage range and ultra-accuracy. It is widely employed in many end-applications such as portable devices and automotive electronics, as its robust features and high reliability make it an ideal choice for many designs. Its main purpose is to monitor the system voltage and to reset the system in case of a failure, which it accomplishes by using its internal voltage monitor circuit and timer circuit.
