The CAT1162WI25 is a low operating voltage, fast turning and low power logic voltage supervisor. It is a single-output supervisory circuit which holds a dedicated logic circuit in a reset condition until the supply voltage applied to VCC reaches the reset threshold, indicated in the datasheet. This important application is widely used in communications and other electronic systems, where reliable reset capability is paramount.

The CAT1162WI25 performs its reset function by monitoring the voltage applied to the VCC terminal and comparing it to the reset threshold (VTH). When VCC reaches VTH or below, an internal N-Channel MOSFET turns on, allowing the RESET signal to reach a state of logic LOW, indicating system reset. When VCC rises above VTH, the internal MOSFET turns off, and the RESET signal goes to logic HIGH, releasing the system reset status. One of the primary advantages of the CAT1162WI25 is its low operating voltage of 1.7V and its fast turn-on time of only 4µs.

The CAT1162WI25 is suitable for a variety of power management and voltage supervisor applications, including power up/down sequencing and host reset logic. In addition, it incorporates other important features, such as power-on reset, over-voltage lockout, short-circuit protection, under-voltage lockout, and hysteresis, making it an ideal supervisory solution for many industrial and consumer applications.

The CAT1162WI25 is designed for single-output applications, such as power supplies or embedded systems, where reliable logic reset protection is essential. It uses an advanced 4-bit CMOS logic chip, which provides high speed operation, low power consumption and wide voltage input range. It features 2-kV ESD protection, is fully powered down for low power consumption, and configurable reset timing. In addition, it is able to hold high-internal input static current of only 116µA, resulting in low quiescent power consumption and improved system reliability.

The CAT1162WI25 is available in a standard 8-pin PowerPAD package and is able to meet a variety of industrial and consumer voltage supervisor needs. The integrated reset output can be used to guarantee a known system logic state on power-up, and it can be configured to provide a reset signal to a variety of devices, such as CPUs, memory, microprocessors, digital signal processors (DSPs), and ASICs. Consequently, it provides a reliable reset mechanism for any system that relies on one.

In summary, the CAT1162WI25 is a low voltage, fast turn-on and low power logic voltage supervisor with a wide range of applications. It is an essential device for any application requiring reliable logic reset protection and it is an ideal voltage supervisor solution for many industrial and consumer applications. The CAT1162WI25 is easy to use and configure, making it an excellent choice when selecting a reliable supervisory device for your system.
