The SG Micro Corp SGM811-RXKA4/TR is a supervisory integrated circuit that monitors power supply voltages in microprocessor and digital systems. It is designed to monitor various voltage levels including 1.8V, 2.5V, 3V, 3.3V, and 5V. The device provides a reset output during power-up, power-down, and brownout conditions, with an internal timer holding the reset asserted for 240ms on power-up.
Key features include reset assertion down to 1V VCC, a minimum power-on reset time of 150ms, and a low power consumption of 13μA typical. The SGM811 series offers a manual reset input, which is useful for user-initiated system resets. This specific part, SGM811-RXKA4/TR, has a reset threshold of 2.63V.
The SGM811/SGM812 devices are available in SOT-143 and SOT-23-5 packages, suitable for surface mount applications. These supervisory circuits are designed for use in microprocessor systems, controllers, intelligent instruments, automotive systems, safety systems, and portable instruments.
