Description

General part information

TPS3306-Q1 Series

The TPS3306 family is a series of supervisory circuits designed for circuit initialization which require two supply voltages, primarily in DSP and processor-based systems.

The product spectrum of the TPS3306-xx is designed for monitoring two independent supply voltages of 3.3 V/1.5 V, 3.3 V/1.8 V, 3.3 V/2 V, 3.3 V/2.5 V, or 3.3 V/5 V.

The various supervisory circuits are designed to monitor the nominal supply voltage, as shown in the following supply-voltage monitoring table.
