Texas Instruments TPS3307-33DR

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, RESET is asserted when the supply voltage VDDbecomes higher than 1.1V. Thereafter, the supply voltage supervisor monitors the SENSEn inputs and keeps RESET active as long as SENSEn remain 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) = 200ms, starts after all SENSEn inputs have risen above the threshold voltage VIT+. When the voltage at any SENSE input drops below the threshold voltage VIT-, the RESET output becomes active (low) again.

The TPS3307-xx family of devices incorporates a manual reset input, MR. A low level at MR causes RESET to become active. In addition to the active-low RESET output, 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.
