The CAT803JSDI-GT3 is a power supply supervisor from Quarktwin Technology Ltd. designed to monitor voltage levels in digital systems. It generates a reset signal when the power supply voltage falls below a specified threshold and maintains this signal for at least 140 ms after the voltage returns to normal. This device is a direct replacement for the MAX803 and operates over an industrial temperature range of -40¬8C to +85¬8C. The CAT803 features an open-drain RESET output that is active LOW, requiring an external pull-up resistor. It supports various standard threshold levels for power supplies, including +5.0 V, +3.3 V, +3.0 V, and +2.5 V, with custom reset threshold values available. The device is capable of functioning with supply voltages as low as 1.0 V and has a low power supply current of 6 ¬µA. It is available in compact SOT-23 and SC-70 packages and is compliant with RoHS standards. Applications for the CAT803 include computers, servers, laptops, wireless communications, and embedded control systems, making it suitable for a wide range of electronic projects.
