The SG Micro Corp SGM803-SXN3L/TR is an integrated microprocessor supervisory device designed to improve system stability and accuracy. It provides reliable reset assertion during power-up, power-down, and brownout conditions, even when VCC drops as low as 1V.
Key electrical features include a low quiescent current of 13μA typical, making it suitable for battery-powered applications. It supports multiple reset threshold voltage options, including 1.8V, 2.5V, 3V, 3.3V, and 5V, and features excellent transient immunity.
This device is available in a compact SOT-23-3 package and operates across a wide ambient temperature range of -40°C to +125°C. The SGM803 variant specifically offers an open-drain RESET output that requires a pull-up resistor.
Applications for this supervisory circuit include computers, portable equipment, automotive systems, controllers, and critical power monitoring in microprocessors.
The SGM803 series offers reset threshold voltage options for 1.8V, 2.5V, 3V, 3.3V, and 5V.
