The CAT825TTDI-GT3 is a Supervisors module from the Power Management Integrated Circuit (PMIC) lineup of products. These devices provide battery and system monitoring, power on/off sequencing and system protection that can be used in a variety of commercial and industrial applications.

The CAT825TTDI-GT3 is a highly integrated, dual input, multi-channel supervisor and sequencing device with integrated system monitoring and protection functions. The monitor and protection functions include dual-channel inputs with resistive or inductive pullups, channel-configured brownout or power-fail comparator, channel-configured temperature comparator, channel-programmable rechargeable battery undervoltage monitoring and protection, and adjustable internal delay time for measurement and protection functions. The on/off sequencing and control functions include software-programmable system power on/off sequencing, overvoltage protection (OVP), overcurrent protection (OCP), and over-temperature protection (OTP). In addition, the CAT825TTDI-GT3 provides four module-level system control channels, two which are controllable by the master device and two which are controllable by the secondary master device.

The CAT825TTDI-GT3 is designed to protect system components against overvoltages, overcurrents, and over-temperatures. It can also be used to sequence various system power levels and provide power control. It features an advanced rechargeable battery undervoltage monitor and protection circuit that offers adjustable UVLO thresholds and adjustable hysteresis levels. This feature has the capability to detect the presence of a rechargeable battery, or a battery in need of charging, and can also report the battery\'s health. The device also features adjustable temperature-comparator thresholds for optimal over-temperature protection.

The CAT825TTDI-GT3 is designed with an integrated, analog-controlled switching architecture that enables fast, easy, and precise control of the power switch in response to system events. This architecture provides a comprehensive solution for applications such as multi-port, multi-voltage converters, multiple-output power supplies, and hot-swap controller. In addition, the CAT825TTDI-GT3 includes two built-in watchdog timers, one programmable and one fixed-time-out type, that can be used to detect memory faults and provide system reset.

The CAT825TTDI-GT3 is engineered with several protection- and control-oriented modes that provide protection against overvoltage, overcurrent, over-temperature, and undervoltage. The module also incorporates multiple level system verification and latch-off mode to extend system lifetimes. In addition, advanced features, such as slew-rate control, are integrated in the CAT825TTDI-GT3. The device also provides an additional error-report and system recovery features.

The CAT825TTDI-GT3 is perfect for applications that require precision control of power states and regulators, as well as robust system protection against power supply faults and environmental conditions. The device is designed with an overvoltage and overcurrent protection to ensure safe and reliable operation. With the addition of an adjustable temperature-comparator threshold and low-dropout regulator, the device can be programmed to provide maximum flexibility and protection.

With its advanced design, the CAT825TTDI-GT3 has extended utility in a variety of applications, such as portable devices, servers, and other systems requiring precision control of power states and regulators, and robust system protection against power supply faults and environmental conditions. By incorporating all these features in a single module, the CAT825TTDI-GT3 is the ideal solution for applications where system reliability and performance is mission-critical.
