The APX803S-23SA-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 specified threshold, maintaining the reset signal for a minimum of 1ms after VCC returns 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. With a typical supply current of 10µA, the APX803S is particularly well-suited for portable and battery-powered applications. It operates effectively with VCC down to 1V and is designed to ignore fast transients on the power supply. The device is available in a compact 3-pin SOT23 package and is fully RoHS compliant, making it an environmentally friendly choice. The APX803S is ideal for applications such as computers, controllers, intelligent instruments, and critical microprocessor power monitoring.
