ON Semiconductor CAT803SSDI-GT3 Voltage Supervisor

The CAT803SSDI-GT3 is a highly reliable voltage supervisor device designed by ON Semiconductor, a leader in energy-efficient innovations. This compact component plays a critical role in system reliability by monitoring the power supply voltage in digital systems and microprocessor-based applications. It ensures that the system operates within the acceptable voltage thresholds, providing an extra layer of protection against unpredictable power fluctuations.

This voltage supervisor is tailored for portable and battery-powered equipment, where maintaining the correct operation voltage is crucial for the integrity and longevity of the device. The CAT803SSDI-GT3 offers a precise monitoring voltage threshold of 3.08V, which is ideal for 3.3V powered systems. It features an active-low reset output, which remains asserted until the system voltage has stabilized above the reset threshold, ensuring that the system has adequate power before beginning operation.

The device boasts a low power consumption, making it an excellent choice for power-sensitive designs. It also has a fast response time, which is vital for quickly reacting to under-voltage conditions and preventing potential damage to the system or data loss. The CAT803SSDI-GT3 comes in a small 3-pin SOT-23 package, which is advantageous for designs with limited board space.

Additional features of the CAT803SSDI-GT3 include a built-in delay time which prevents false triggering due to transient conditions, and the ability to operate over a wide temperature range of -40°C to +85°C, making it suitable for various environments and applications. The device is also characterized for operation from a low voltage of 1.0V, which allows for early system voltage monitoring during power-up sequences.

With its combination of precision voltage monitoring, low power consumption, and compact form factor, the ON Semiconductor CAT803SSDI-GT3 is an essential component for enhancing system stability and reliability. It is a practical solution for designers looking to safeguard their electronic products against the risks associated with low voltage conditions.
