CAT1025YI-30-GT3

The CAT1025YI-30-GT3 is a voltage supervisor PMIC that specializes in undervoltage detection and providing system power management. This device includes a precision voltage reference, comparator and programmable reset delay. It is a low-power device and can be used to provide system power management in a range of applications.

The CAT1025YI-30-GT3 is able to detect deviations in voltage levels as small as 3.2 mV. It is commonly used in applications such as servers, industrial control, networking, audio processing and other embedded systems. It is designed to be highly reliable and able to protect a system against overvoltage, undervoltage and overcurrent conditions.

The CAT1025YI-30-GT3 provides system power management by providing voltage supervision. The device monitors the supply voltage, and when it drops below a certain predetermined threshold it triggers a reset. The exact threshold can be programmed through external resistors. The device also provides an open-drain reset output and can be used with an external pull-up resistor. Reset duration can be adjusted and set down to 1 μs, making the CAT1025YI-30-GT3 suitable for high-performance applications.

The CAT1025YI-30-GT3 also offers selectable power-on reset delay times. This allows the system to power up gradually, reducing the inrush current when the system first powers on. The CAT1025YI-30-GT3 also monitors the system supply and protects it against overvoltage and overcurrent conditions. It has an adjustable overvoltage threshold and adjustable overcurrent threshold. When either condition is detected the device will trigger a reset.

In addition to the CAT1025YI-30-GT3‘s voltage supervision, it provides an independent watchdog timer (WDT). The WDT can be set from 4 ms up to 1024 ms and can be used to detect system lockups or software faults. If a fault is detected the device will trigger a reset and the system can be restarted.

The CAT1025YI-30-GT3 is a highly versatile device and can be used to provide powerful system power management in a range of applications. Its features include a precision voltage reference, comparator, adjustable threshold voltage, adjustable reset delay, watchdog timer and adjustable overvoltage and over current monitoring, making it ideal for a range of applications.
