The BL8518CB3TR263DC is a microprocessor and microcontroller supervisor manufactured by Belling. It is a SOT-23 RoHS compliant device and is designed to regulate and protect circuits from damaging overvoltage or undersupply conditions. It is able to set up an upper threshold voltage of 3.263V which will be maxed out at a power supply current of 1.6A. Additionally, the device will prevent reset false triggering which allows for faster start-up times and a higher level of system reliability.
