The APX809S-40SR-7 is a microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It asserts a reset signal when the VCC supply voltage drops below a preset threshold and maintains this signal for at least 240 milliseconds after the voltage returns above the threshold. This device is suitable for various supply voltages, including +2.5V, +3.0V, +3.3V, and +5V, and features a push-pull active low RESET output. The APX809S-40SR-7 operates with a typical supply current of 7µA, making it ideal for portable and battery-powered applications. It is available in a compact 3-pin SOT23 package and is fully RoHS compliant, ensuring it meets environmental standards. The device is designed to ignore fast transients on VCC and guarantees correct output logic states down to a VCC of 1V. This product is suitable for applications in computers, controllers, intelligent instruments, and critical microprocessor power monitoring.
