The CN809L is an electronic component manufactured by Consonance, which is a SOT23-3 RoHS-compliant PMIC (Power Management Integrated Circuit) designed to provide a supervisor solution in microcontrollers, DSPs and other low and high power systems. It features three thresholds: positive voltage monitoring, negative voltage monitoring, and manual reset monitoring. It also features an output enable pin that can be used to override the manual reset to cause an output active. It supports a supply voltage range of 3.0V to 5.5V with low power consumption and a wide temperature range from -40°C to +85°C.
