ON Semiconductor CAT812LTBI-GT3: Voltage Supervisor IC

The ON Semiconductor CAT812LTBI-GT3 is a high-performance, precision voltage supervisor designed to ensure reliable operation and system protection in a variety of applications. This device is particularly suited for use in microprocessor, microcontroller, and other logic system applications where it is crucial to monitor the power supply voltage to safeguard system integrity.

The CAT812LTBI-GT3 is part of ON Semiconductor's portfolio of voltage supervisor ICs that offer a cost-effective solution for monitoring voltage levels and providing a reset signal to the host system upon detection of out-of-tolerance conditions. The device features a fixed threshold voltage that has been factory-programmed to ensure accurate monitoring without the need for external components.

Key features of the CAT812LTBI-GT3 include:

• Fixed Threshold Voltage: The device comes with a preset threshold voltage, which simplifies design and reduces component count.
• Low Power Consumption: Designed for efficiency, the IC consumes minimal power, making it ideal for battery-operated devices.
• Reset Timeout Delay: The built-in delay ensures that the system has adequate time to stabilize before returning to operation, preventing system errors due to premature resets.
• Manual Reset Input: This feature allows for a manual system reset, providing additional control to the user or system administrator.
• Compact SOT-23 Package: The small footprint of the SOT-23 package enables integration into space-constrained designs without compromising performance.
• Wide Operating Temperature Range: The IC is operational over a broad temperature range, ensuring reliability across various environmental conditions.

The CAT812LTBI-GT3 voltage supervisor is designed with an open-drain reset output, which remains asserted until the monitored voltage rises above the threshold and the reset timeout period has elapsed. This ensures that the system has enough time to recover and prevents false triggers that can lead to system instability.

With its robust feature set and ON Semiconductor's reputation for quality, the CAT812LTBI-GT3 is a reliable choice for designers looking to enhance system reliability through precise voltage monitoring and reset functionality.
