DIODES Incorporated Supervisory Circuits PT7A7612S-13

The PT7A7612S-13 is a microprocessor supervisory circuit designed to enhance the reliability and accuracy of power-supply systems in microprocessor applications. It features a precision supply-voltage monitor with a threshold of 4.38V, ensuring effective monitoring of power conditions. The device asserts a reset output during power-up, power-down, and brownout conditions, which is critical for maintaining system stability. This supervisor circuit includes a debounced manual-reset input and a power-fail voltage monitor input that triggers a low output when the voltage falls below 1.25V. The reset output is active-low and provides a guaranteed valid signal at a supply voltage of 1V. The PT7A7612S-13 is also fully RoHS compliant and free from halogens and antimony, making it suitable for environmentally conscious designs. Applications for this device include computers, controllers, intelligent instruments, and portable battery-powered equipment, making it a versatile choice for various engineering projects.
