ON Semiconductor CAT811LTBI-GT3 Voltage Supervisor IC

The CAT811LTBI-GT3 is a high-performance microprocessor supervisory circuit designed by ON Semiconductor to enhance system reliability in a wide array of electronic applications. This compact and efficient component is specifically engineered to monitor the power supply voltage of digital systems, ensuring that the system operates within the acceptable voltage range and providing a reset signal to the microprocessor during power-up, power-down, or brown-out conditions.

The device is characterized by its precision voltage monitoring capability, which is crucial for systems that require consistent and reliable operation. The CAT811LTBI-GT3 has a preset threshold voltage of 4.63V, making it suitable for 5V-powered applications. This threshold accuracy is maintained over the entire operating temperature range and supply voltage, ensuring the device's reliability under varying conditions.

Featuring a low supply current of only 9 µA, the CAT811LTBI-GT3 is an energy-efficient solution that contributes to the overall power conservation of the system it is integrated into. The device comes in a 5-pin SOT-23 package, which is ideal for space-constrained applications, providing a compact footprint without compromising on performance.

Key functionalities of the CAT811LTBI-GT3 include a manual reset input, which allows the system to be reset by an external signal, and a reset timeout period of 140 ms minimum, ensuring the system has adequate time to stabilize after a reset event. The device also features an active-low reset output, which remains asserted until the system voltage has stabilized and the timeout period has elapsed, providing an additional layer of protection for the system's processor.

With its robust design and precise voltage monitoring, the CAT811LTBI-GT3 is an excellent choice for use in microprocessor systems, computers, controllers, and other intelligent systems where reliable voltage supervision is critical. ON Semiconductor's commitment to quality ensures that this voltage supervisor IC will contribute significantly to the stability and performance of your electronic systems.
