The TPS3305 family is a series of micropower supply voltage supervisors designed for circuit initialization. Its dual monitor topology is well-suited to use in DSP and processor-based systems, which often require two supply voltages, core and I/O.

RESET is asserted when the voltage at either SENSEn pin falls below its threshold voltage, V_IT. When both SENSEn pins are again above their respective threshold voltages, RESET is held low for the factory-programmed delay time (200ms typ). RESET is also asserted if the watchdog input (WDI) is not toggled for more than 1.6s typ.

The TPS3305-xx devices are available in either 8-pin MSOP or SO packages, and are specified for operation over a temperature range of -40°C to +85°C.
