PMIC - SupervisorsA supervisor is an integrated circuit that is used to supervise the power supply of a device. The CAT1026LI-25-G is one type of supervisor circuit. It is designed to provide improved system reliability, accuracy, and efficient delivery of power to the device it is supervising.The CAT1026LI-25-G is a two-channel supervisor IC designed for use in high-end applications such as industrial equipment, datacenter, and embedded systems. It is designed to provide accurate monitoring of two power supply output voltages, as well as control its associated power supply. It is also designed to provide error-free monitoring for up to 32 peripheral power supplies, as well as monitor and control power supply sequencing.The CAT1026LI-25-G includes a robust set of features that help ensure proper system operation, including active current and voltage monitoring, temperature monitoring, and power-on reset (POR) generation. It also contains an extensive set of protection features that prevent system failures due to a variety of factors, such as overvoltage, overcurrent, open-wire faults, and reverse polarity.The CAT1026LI-25-G is also capable of providing system soft-start control and power supply sequencing. It includes a dedicated input pin for power monitoring of a connected system, as well as an output pin for resetting the system when an unusual condition is detected.The CAT1026LI-25-G is designed to operate over a wide range of operating currents and temperatures, from -40°C to +95°C. It is also designed to operate within a wide range of input and output voltages, from 4.5V to 28V. It can also operate over a wide range of operating frequencies, from 0.8MHz to 2.5MHz.The working principle of the CAT1026LI-25-G is based on the monitoring of two power supply outputs and the control of their associated power supply. The two outputs are connected to a comparator, which monitors for overvoltage, overcurrent, open-wire faults, and reverse polarity. When unusual conditions are detected, the output pin will be activated to reset the system. It also has a dedicated input pin for power monitoring, which monitors for stability and protection from from overcurrent and overvoltage.The CAT1026LI-25-G is primarily used in high-end applications that require the high accuracy and dependability of a two-channel voltage supervisor. It is used in industrial equipment, datacenter, and embedded systems, as well as in various types of specialty equipment. It can also be used in applications that require the power supply sequencing control that this device is capable of providing.
