Description

The TPS3307 family is a series of micropower supply voltage supervisors designed for circuit initialization primarily in DSP and processor-based systems, which require more than one supply voltage. The product spectrum of the TPS3307-xx is designed for monitoring three independent supply voltages: 3.3V/1.8V/adj, 3.3V/2.5V/adj or 3.3V/5V/adj. The adjustable SENSE input allows the monitoring of any supply voltage >1.25V. The various supply voltage supervisors are designed to monitor the nominal supply voltage. During power-on,RESETis asserted when the supply voltage VDDbecomes higher than 1.1V. Thereafter, the supply voltage supervisor monitors the SENSEninputs and keepsRESETactive as long as SENSEnremain 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)= 200ms, starts after all SENSEninputs have risen above the threshold voltage VIT+. When the voltage at any SENSE input drops below the threshold voltage VIT-, theRESEToutput becomes active (low) again. The TPS3307-xx family of devices incorporates a manual reset input,MR. A low level atMRcausesRESETto become active. In addition to the active-lowRESEToutput, the TPS3307-xx family includes an active-high RESET output. The devices are available in either 8-pin MSOP or standard 8-pin SO packages. The TPS3307-xx devices are characterized for operation over a temperature range of -40°C to +85°C.
