ON Semiconductor CAT825MTDI-GT3 Voltage Supervisor

The ON Semiconductor CAT825MTDI-GT3 is a precision voltage supervisor designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. This device ensures that the system's microprocessor, or other critical components, are reset and brought into a known state during power-up, power-down, or brown-out conditions.

Key Features

• Voltage Threshold Accuracy: The CAT825MTDI-GT3 has a tightly controlled threshold voltage accuracy of ±1.5%, ensuring reliable monitoring of power supply levels.
• Low Power Consumption: This device is optimized for low power consumption, making it suitable for battery-operated applications.
• Manual Reset Input: A manual reset input is provided, allowing the user to trigger a reset pulse with an external signal.
• Reset Timeout: The reset output is asserted for a fixed timeout period after VCC has risen above the reset threshold, ensuring the system has adequate time to stabilize.
• Operating Temperature Range: The CAT825MTDI-GT3 operates over a wide temperature range, making it suitable for industrial applications.
