The APX803S-44SR-7 is a microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It asserts a reset signal during power-up and whenever the supply voltage (VCC) drops below a preset threshold, maintaining the reset signal for a minimum of 1ms after VCC rises above the threshold. This device is suitable for various supply voltages, including 2.5V, 3.0V, 3.3V, and 5.0V, and features an open-drain active low RESET output. The APX803S-44SR-7 operates with a typical supply current of 10µA, making it ideal for portable and battery-powered applications. It is available in a 3-pin SOT23 package and is fully RoHS compliant, ensuring it meets environmental standards. The device is capable of functioning correctly with VCC down to 1V and is designed to ignore fast transients on the power supply. Its applications include computers, controllers, intelligent instruments, and critical microprocessor power monitoring.
