Processor Supervisor 2.66V 2.63V 4-Pin SOT-143 T/R

The PT7M78xx family microprocessor (µP) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in µP systems. These devices reduce the complexity and number of components required to monitor power-supply and battery functions.
