The APX803-44SRG-7 from Diodes Incorporated is a 3-pin microprocessor supervisory circuit. It is designed to monitor power supply voltages in microprocessor and digital systems, ensuring reliable operation. This device asserts a reset signal on power-up and when the VCC supply voltage drops below a preset threshold.
Key electrical specifications include a nominal voltage of 4.38V, an active low open-drain reset output, and a minimum reset timeout of 140ms. The output is guaranteed to remain in a correct logic state for VCC down to 1V. The typical supply current is 30µA, making it suitable for portable equipment. The reset pulse duration is typically 2ms.
This supervisor IC is housed in a SOT-23-3 package, suitable for surface mount applications. It operates over a temperature range of -40°C to 85°C. The device is designed to eliminate the need for external components, simplifying circuit design and reducing costs.
Applications include critical microprocessor and micro-controller power monitoring in computers, controllers, intelligent instruments, and battery-powered equipment.
