Texas Instruments TPS3705-50DGNR
The TPS370x-xx family of microprocessor supply-voltage supervisors provide circuitinitialization and timing supervision, primarily for DSP and processor-based systems.
During power-on, RESET is asserted when the supply voltageVDD becomes higher than 1.1 V. Thereafter, the supply voltage supervisormonitors VDD and keeps RESET active as long asVDD remains below the threshold voltage VIT+. Whenthe supply voltage drops below the threshold voltage VIT–, the outputbecomes active (low) again. No external components are required. All the devices of this familyhave a fixed-sense threshold voltage VIT– set by an internal voltagedivider.
The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. Thecircuits are available in either 8-pin MSOP or standard SOIC packages. The TPS370x-xx devices arecharacterized for operation over a temperature range of −40°C to 85°C.
