ON Semiconductor CAT810SEUR-T Voltage Supervisor
The ON Semiconductor CAT810SEUR-T is a precision voltage supervisor designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. This ensures the system operates reliably within its voltage thresholds. The device is an essential component for any microprocessor, microcontroller, or digital system that requires a reset signal in the event of a power failure or dip below a certain voltage level.
Featuring a 3-pin SOT-23 package, the CAT810SEUR-T is compact and suitable for space-constrained applications. It offers a threshold voltage of 4.38V, which makes it ideal for 5V operated systems, ensuring that the device will trigger a reset if the supply voltage drops below this threshold. The reset timeout period is approximately 140ms, giving the system sufficient time to stabilize before resuming operation.
The CAT810SEUR-T provides an active low reset output, which means the reset signal is asserted ('0') when the monitored voltage is below the specified threshold and deasserted ('1') when the voltage is above the threshold. This is particularly useful for interfacing with microcontrollers that require an active low signal to initiate a reset sequence.
One of the key features of the CAT810SEUR-T is its low power consumption, making it a suitable choice for battery-powered and portable devices where power efficiency is critical. Additionally, the device's built-in hysteresis prevents false triggering due to minor voltage fluctuations, ensuring stable and reliable operation.
With its wide operating temperature range from -40°C to 85°C, the CAT810SEUR-T can be deployed in various environments, from industrial to commercial applications. Its robust design and high accuracy make it an excellent choice for system designers looking for a reliable voltage monitoring solution.
Overall, the ON Semiconductor CAT810SEUR-T is a highly reliable and precise voltage supervisor that offers essential protection for digital systems. By monitoring the supply voltage and providing a timely reset signal, it helps maintain system integrity and prevents data corruption due to unexpected power issues.
