ON Semiconductor CAT809JTBI-GT3 Voltage Supervisor IC

The CAT809JTBI-GT3 from ON Semiconductor is a high-performance microprocessor (µP) supervisory circuit designed to keep a system's microcontroller in reset until the system voltage has stabilized at the correct level for reliable operation. This precision voltage supervisor IC is an essential component for systems that require a stable and reliable operation upon power-up or during a brown-out condition.

Key Features

• Precision Monitoring: With tight precision monitoring of 3V, 3.3V, and 5V supply voltages, the CAT809 ensures that the system’s supply voltage is accurately supervised to prevent erroneous operation.
• Low Power Consumption: Designed for low-power operation, this IC consumes minimal power, making it ideal for battery-operated and power-sensitive applications.
• Manual Reset Input: The device includes a manual reset input that allows the user to trigger a system reset, providing additional control over the system's operation.
• Reset Timeout: It features a 140 ms minimum reset timeout delay, ensuring that the system has sufficient time to stabilize before coming out of reset.
• Wide Operating Temperature Range: The CAT809JTBI-GT3 is operational over a temperature range of -40°C to +85°C, accommodating various environmental conditions.
