CAT1320WI-28-GT3 is a programmable overvoltage and overcurrent protection IC, which is a type of supervisory circuit. This IC was specifically designed to provide protection for electronic systems across different sectors such as automotive, industrial, and communication systems, as well as hand-held devices such as smartphones and tablets. It provides a reliable and cost-effective solution to monitor input voltage, detect input power-up/power-down faults, and perform programmable overvoltage and overcurrent protection routines.

CAT1320WI-28-GT3 can be used to detect and respond automatically to any overvoltage or overcurrent conditions, such as system brownouts, overcurrent faults, input surge conditions, unregulated input voltages, or accidental shorts. It can be programmed to provide protection against any of these conditions by setting the low, high, and reset trip thresholds. The IC also contains a temperature warning, which can be used to provide additional protection against heat-related damage and failures.

The CAT1320WI-28-GT3 supervisor operates in 2 distinct modes: active power on reset and power off reset. In active POR mode, the IC uses an internal voltage reference, along with external inputs, to provide power-on and power-off reset signals. The device also utilizes an internal comparator, which monitors the voltage level after power up and trips the device when it reaches a programmed voltage level. Once this level is reached, the IC will initiate a reset event, thereby protecting the circuitry from any overvoltage or overcurrent conditions that may have occurred during power up.

In power-off reset mode, the IC monitors the voltage level during power shutdown and compares it to a programmed voltage level to determine if a reset event is required. If so, the IC will safely shut down the system, thereby preventing any potential damage from occurring.

CAT1320WI-28-GT3 also implements additional features to further improve its performance including an open-drain output, adjustable reset thresholds, programmable power reduction mode, over heat warning, reverse voltage protection, and a built-in watch dog timer for monitoring system activity. This provides a reliable power protection solution for any application.

CAT1320WI-28-GT3 is available in a small, space-saving 8-pin PSSOP package, making it perfect for use in a variety of applications. It offers overvoltage and overcurrent protection to ensure that any system is safe from damage and operational interruptions, and its programmable features can be customized to meet the requirements of any particular application.

CAT1320WI-28-GT3 is suitable for use in automotive, industrial, and communication systems, as well as hand-held devices such as smartphones and tablets. It is a reliable and cost-effective solution for providing overvoltage and overcurrent protection for any system, and its additional features greatly improve its performance.
