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. During power-on,RESETis asserted when the supply voltage VDDbecomes higher than 1.1 V. Thereafter, the supervisory circuits monitor the SENSEn inputs and keepRESETactive as long as SENSEn remains below the threshold voltage VIT. An internal timer delays the return of theRESEToutput 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. The integrated power-fail (PFI) comparator with separate open-drain (PFO) output can be used for low-battery detection, power-fail warning, or for monitoring a power supply other than the main supply. The TPS3306-xx devices integrate a watchdog timer that is periodically triggered by a positive or negative transition of WDI. When the supervising system fails to retrigger the watchdog circuit within the time-out interval, tt(out)= 0.50 s,RESETbecomes active for the time period td. This event also reinitializes the watchdog timer. Leaving WDI unconnected disables the watchdog. The TPS3306-xx devices are available in either 8-pin MSOP or standard 8-pin SO packages, and are characterized for operation over a temperature range of -40°C to +85°C.

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. During power-on,RESETis asserted when the supply voltage VDDbecomes higher than 1.1 V. Thereafter, the supervisory circuits monitor the SENSEn inputs and keepRESETactive as long as SENSEn remains below the threshold voltage VIT. An internal timer delays the return of theRESEToutput 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. The integrated power-fail (PFI) comparator with separate open-drain (PFO) output can be used for low-battery detection, power-fail warning, or for monitoring a power supply other than the main supply. The TPS3306-xx devices integrate a watchdog timer that is periodically triggered by a positive or negative transition of WDI. When the supervising system fails to retrigger the watchdog circuit within the time-out interval, tt(out)= 0.50 s,RESETbecomes active for the time period td.

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. The integrated power-fail (PFI) comparator with separate open-drain (PFO) output can be used for low-battery detection, power-fail warning, or for monitoring a power supply other than the main supply. The TPS3306-xx devices integrate a watchdog timer that is periodically triggered by a positive or negative transition of WDI. When the supervising system fails to retrigger the watchdog circuit within the time-out interval, tt(out)= 0.50 s,RESETbecomes active for the time period td. This event also reinitializes the watchdog timer. Leaving WDI unconnected disables the watchdog. The TPS3306-xx devices are available in either 8-pin MSOP or standard 8-pin SO packages, and are characterized for operation over a temperature range of -40°C to +85°C.

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. During power-on,RESETis asserted when the supply voltage VDDbecomes higher than 1.1 V. Thereafter, the supervisory circuits monitor the SENSEn inputs and keepRESETactive as long as SENSEn remains below the threshold voltage VIT. An internal timer delays the return of theRESEToutput to the inactive state (high) to ensure proper system reset.
