MaxLinear, Inc. Supervisors SP809EK-L-4-6/TR

The SP809EK-L-4-6/TR is a low power microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It features a guaranteed reset valid down to a supply voltage of 0.9V, making it suitable for applications where low voltage operation is critical. The device asserts a reset signal for at least 140ms after the supply voltage has risen above the reset threshold, ensuring reliable operation during power fluctuations. With an ultra-low supply current of 1OºA, the SP809 is ideal for portable electronic devices, including digital cameras and electrical power meters. It is available in a compact 3-pin SOT-23 package, which facilitates integration into space-constrained designs. The device offers internally fixed reset thresholds of 2.3V, 2.6V, 2.9V, 3.1V, 4.4V, and 4.6V, with a voltage threshold tolerance of 1.5%. The SP809EK-L-4-6/TR is suitable for engineers looking for a reliable and efficient supervisory solution for their projects.
