CN809R with PMIC - Supervisors SOT23-3 RoHS is an integrated circuit (IC) designed and manufactured by Consonance with a ±0.3V precision reset monitoring voltage, suitable for a variety of microcontroller use, such as microprocessor system supervisors, processors, and microcontrollers. The IC has a supply voltage range of 2.0V to 5.5V and a three-pin SOT23-3 package, which is RoHS compliant. It is designed to prevent system lockup in a microprocessor system, offering system reset and manual reset or reset hold functions with an active-low reset output. With its fast rising time of 4ms and adjustable timeout of up to 180ms, the IC is capable of providing a reliable low-power system reset in the event of power failure, CPU lockup, or an unexpected system fault. The CN809R with PMIC Supervisors SOT23-3 RoHS is an ideal solution for microprocessor system supervisors, and is suitable for a wide range of applications.
