DESCRIPTION
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.
During power-on, RESET\ is asserted when the supply voltage V DD becomes higher than 1.1 V. Thereafter, the supervisory
circuits monitor the SENSEn inputs and keep RESET\ active as long as SENSEn remains below the threshold voltage VIT.
An internal timer delays the return of the RESET\ output to the inactive state (high) to ensure proper system reset. The
delay time, td(typ) = 100 ms, starts after SENSE1 and SENSE2 inputs have risen above the threshold voltage VIT. When the
voltage at SENSE1 or SENSE2 input drops below the threshold voltage VIT, the output becomes active (low) again.
