PMIC supervisors are a type of integrated circuit (IC) that monitors the critical system functions of a specific electronic product. Specifically, these supervisors monitor, control and protect the circuits within the power and/or memory/communication systems. The CAT8801ZSD-GT3 is one of the most advanced of PMIC supervisors and is used in a variety of applications. This article will discuss the application field and working principle of the CAT8801ZSD-GT3.

Applications

The CAT8801ZSD-GT3 PMIC supervisor is designed for a range of applications including, but not limited to, industrial, automotive, cellular and consumer electronics. It supports a range of functions such as monitoring and configuring system voltages, low power reset and programmable I/O. Its flexible design means that it can be used in a range of different systems.

The CAT8801ZSD-GT3 is ideal for automotive applications such as body electronics, powertrain control, lighting, engine control and aftermarket applications. It is also used in mobile phones, digital cameras, MP3 players and other personal electronic devices. It is equally suited for use in industrial counters, meters, robotics and other similar systems. In fact, its applicability covers virtually any system where power and/or memory/communication protection is required.

Features

The CAT8801ZSD-GT3 PMIC supervisor is a highly integrated system-on-chip (SoC) solution that includes multiple power and/or memory/communication monitor, control and protection functions. It includes a precision voltage detector with programmable thresholds, a reset circuit, an I/O expander, an address counter/timer, a temperature monitor and a watchdog timer.

It supports programmable I/O with interrupt capability, input pin debounce, address counter/timer with alarm triggering, hardware reset and interrupt triggering, and a power detection circuit for battery-backed applications. It also includes programmable reset sources, such as internal reset after a given time, reset after a given number of cycles, or reset after a given number of valid clock cycles.

The CAT8801ZSD-GT3 is also designed with a range of features to protect sensitive components in digital systems. These include a built-in reset line isolation feature, dual digital die temperature monitor, Two independent reset outputs, voltage range monitoring and a watchdog timer.

Working Principle

The working principle of the CAT8801ZSD-GT3 PMIC supervisor is based on monitoring and controlling system voltages. It provides a stable operating environment for the sensitive components within power and/or memory/communication systems. When the voltage is outside of the specified range, it will generate an alert signal and/or reset the system.

The CAT8801ZSD-GT3 incorporates a precision voltage detector with programmable thresholds. This allows for monitoring of the system inputs and output voltages, and the resetting of the system when the specified threshold is exceeded. It also provides an isolated reset line to ensure reliable resetting of the system, as well as programmable reset sources such as internal reset after a given time, reset after a given number of cycles, or reset after a given number of valid clock cycles.

The CAT8801ZSD-GT3 also incorporates an I/O expander, which provides additional input/output pins to connect devices such as switches, LEDs and other devices. This allows for flexible system configuration and customization. It also includes an address counter/timer and a temperature monitor, providing additional control and system protection.

Conclusion

The CAT8801ZSD-GT3 PMIC supervisor is designed to monitor, control and protect the circuits within power and/or memory/communication systems. It has a wide range of applications, including automotive, cellular, industrial, consumer and aftermarket areas. It includes a number of features such as programmable voltage thresholds, multiple reset sources, an address counter/timer and temperature monitor. Ultimately, it provides a robust and reliable system control solution for a variety of applications.
