Introduction to CAT140021TWI-GT3

CAT140021TWI-GT3 is a CMOS and PMOS power supervisor designed to help protect against over-voltage and over-temperature abnormalities. It monitors both positive and negative voltage inputs, as well as temperature and current, and has an temperature alert function to inform of any potential issues with the supply. It features one low-power Switch Input (SIP) onboard, and can be used for both power-on and power-down control.

Application Field of CAT140021TWI-GT3

The CAT140021TWI-GT3 is a versatile device which can be used in a variety of applications. It is designed primarily for use in data processing systems, industrial control and other high reliability applications, such as Military & Aerospace, Consumer Electronic and Automobile CE Certification. It can also be used in intelligent power circuitry, monitoring and controlling the switching frequency, voltage, current and temperature.

Features of CAT140021TWI-GT3

The CAT140021TWI-GT3 is equipped with many features to ensure reliable operation. Its monitors both positive and negative voltages, up to -0.6V to 16V, and temperature from -30C to +120C. It has an internal input power-on detection circuit, which can detect input voltage from 0V to 5.5V, and output voltage from 1.2V to 3.6V. It also has a soft-start function, to prevent overshoot due to sudden power input or high current consumption. The device supports both SMBus and I2C interfaces, allowing quick, simple access to its features and functions. It also features a low sigma delta modulator designed to capture temperature and current changes and then alert users to potential problems. The device is capable of both active-low and active-high reset control, allowing reset based on input voltage or temperature thresholds.

Working Principle of CAT140021TWI-GT3

The CAT140021TWI-GT3 is designed to provide power-on and power-down reset control based on an external power connection. The device monitors both positive and negative voltage inputs, and is also capable of monitoring current and temperature. When the external power is connected, the device uses an internal input power-on detection circuit to determine the voltage level, and output voltage from 1.2V to 3.6V. The device also monitors any temperature changes, and once the temperature reaches the threshold, the device sends a reset signal. The CAT140021TWI-GT3 also has an active-low and active-high reset control. This allows the device to provide reset control based on input voltage and temperature thresholds. When the power-on voltage reaches its threshold, the device will send a signal to initiate either a reset or power-down protocol, depending on the user’s desired configuration. Additionally, the device can also initiate a reset signal when it detects over-voltage or over-temperature abnormalities.

Conclusion

The CAT140021TWI-GT3 is a highly advanced CMOS and PMOS power supervisor designed to protect against over-voltage and over-temperature abnormalities. It is designed for use in data processing systems, industrial control and other high reliability applications, and is equipped with a variety of features and functions to ensure reliable performance. The device supports both SMBus and I2C interfaces, allowing for quick, simple access to its features and functions. It also has a low sigma delta modulator for capturing temperatures and current changes, and an active-low and active-high reset control for resetting based on voltage or temperature thresholds.
