TPS3306-18 - Texas Instruments

TPS3306-18 DUAL PROCESSOR SUPERVISORY CIRCUITS

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. TYPICAL OPERATING CIRCU.
