onsemi Supervisors CAT809SSDI-T3

The CAT809SSDI-T3 is a power supply supervisor from Quarktwin Technology Ltd. designed to monitor voltage levels in digital systems. It features a push-pull active LOW reset output, ensuring that a reset signal is generated when the power supply voltage falls below a specified threshold and remains asserted for at least 140 ms after the voltage recovers. This device is a direct replacement for the MAX809 and operates effectively within an industrial temperature range of -40¬8C to +85¬8C. The CAT809 supports various standard voltage thresholds, including +5.0 V, +3.3 V, +3.0 V, and +2.5 V, making it versatile for different applications. It has a low power supply current of 6 ¬µA and is available in compact SOT-23 and SC-70 packages. The device is also Pb-free and RoHS compliant, ensuring it meets environmental standards. Applications include computers, servers, laptops, and embedded control systems, making it suitable for a wide range of electronic projects.
