ON Semiconductor CAT809ZTBI-T3 Supervisory Circuit

The ON Semiconductor CAT809ZTBI-T3 is a precision microprocessor supervisory circuit designed to monitor power supplies in digital systems. It provides a crucial function in ensuring system reliability by asserting a reset signal whenever the VCC supply voltage falls below a preset threshold level. This versatile component is ideal for portable electronics, microcontrollers, and other digital systems where power supply stability is essential.

Key Features of CAT809ZTBI-T3

• Reset Threshold Voltage: The device offers a factory-programmed reset threshold voltage, which ensures that it can cater to specific system requirements without the need for external components.
• Reset Timeout: It boasts a reset timeout delay of 140ms (minimum), providing sufficient time for the system to stabilize before allowing the processor to resume operation.
• Low Power Consumption: The CAT809ZTBI-T3 is designed for low power consumption, making it an excellent choice for battery-operated devices where power efficiency is critical.
• Temperature Range: This supervisory circuit operates over a wide temperature range, from -40°C to +85°C, which makes it suitable for use in various environmental conditions.
• Package: It is available in a 3-pin SOT-23 package, providing a compact footprint that is beneficial for space-constrained applications.
• Active-Low Reset Output: The device has an active-low reset output, which remains asserted until the VCC supply voltage returns to an acceptable level and the reset timeout period has elapsed.

Applications

The CAT809ZTBI-T3 supervisory circuit is a versatile component that can be integrated into a wide range of applications, including:

• Microcontroller systems
• Portable and battery-powered devices
